Title
ssldump Heap Buffer Overflow in FAN/1 X.509 Fingerprint Formatting
Summary
The fanx_fingerprint function in ssl/sslxprint.c of ssldump allocates a heap buffer for formatting FAN/1 X.509 certificate fingerprints. The allocation size is computed as strlen(b64) + strlen(hex) + 31, but the format string "fan1:x509:server:passive:%s:sha256:%s" contains 33 fixed characters in addition to the two variable-length fields and a null terminator, requiring strlen(b64) + strlen(hex) + 34 bytes. This miscalculation results in a 3-byte heap-based buffer overflow on every invocation of the function with valid inputs. The overflow occurs because sprintf writes the full formatted string into the undersized heap buffer without bounds checking. An attacker who can supply a crafted pcap file containing a TLS X.509 certificate to a user running ssldump with FAN/1 fingerprinting enabled (for example with the -j -N options) can trigger the overflow. The resulting heap corruption may lead to denial of service through a crash or, in a worst-case scenario, arbitrary code execution in the context of the user running ssldump. The vulnerability is deterministic and requires no special privileges beyond the ability to provide input to the tool.

Fix heap overflow in FAN/1 X.509 fingerprint formatting | 454d108335b2… |
Fix summary
The fix replaces the hardcoded size calculation and unbounded sprintf with a two-step snprintf approach: first computing the exact required output length via snprintf(NULL, 0, format, b64, hex), then allocating precisely that length plus one byte for the null terminator via calloc, and finally writing the formatted string with a bounded snprintf. This eliminates the undersized allocation and guarantees the write never exceeds the allocated buffer.

In ssl/sslxprint.c, the fanx_fingerprint function is modified to extract the format string into a static const array, compute the exact output length using snprintf(NULL, 0, format, b64, hex), allocate fp_len + 1 bytes via calloc, and write with snprintf(fp, (size_t)fp_len + 1, format, b64, hex). A new Python regression test (tests/test_fan1_x509.py) is added that runs ssldump on a sample pcap and verifies each FAN/1 X.509 fingerprint against independently computed base64url and SHA-256 values. CMakeLists.txt is updated to register the test via CTest when Python 3 is available. The GitHub Actions CI workflow is extended to run the test suite and an additional AddressSanitizer-instrumented build to detect invalid buffer accesses.
CVSS rationale
AV:L: The attacker must supply a crafted pcap file to a local instance of ssldump; no network vector is assumed. AC:L: The overflow is deterministic and triggered by any valid X.509 certificate processed through the FAN/1 fingerprint path. AT:N: No special conditions on the target are required. PR:N: No privileges beyond normal user access to run ssldump are needed. UI:A: The user must actively open or process the crafted input file. VC:N: No direct confidentiality impact is evident from a 3-byte heap overflow. VI:H: Heap corruption can lead to arbitrary code execution, compromising integrity. VA:H: Heap corruption can cause a crash, denying service. SC/SI/SA:N: No subsequent system impact is evidenced.
Weakness rationale
- CWE-122 The function allocates a heap buffer via calloc that is 3 bytes smaller than the actual formatted output, and sprintf writes past the end of the allocated region. This is a textbook heap-based buffer overflow caused by an incorrect size calculation.
- CWE-787 The sprintf call writes 3 bytes beyond the end of the heap-allocated buffer, constituting an out-of-bounds write. CWE-122 is the more specific child; CWE-787 is included as the broader category.
Attack pattern rationale
- CAPEC-109 CAPEC-109 describes attacks that exploit programs writing data to buffers without adequate length checking. In this case, the attacker supplies a pcap file containing a TLS X.509 certificate; ssldump processes it and the undersized heap buffer is overflowed by sprintf. The mapping is the closest available CAPEC for a heap buffer overflow triggered by crafted input. Uncertainty: CAPEC-109 is a general pattern and does not specifically call out heap overflows or off-by-N size miscalculations, but no more specific CAPEC exists in the catalog.
Assumptions to verify
- The affected version range is unspecified; the patch does not include version tags or release boundaries. All versions of ssldump containing the vulnerable fanx_fingerprint implementation prior to this commit are assumed affected.
- The attack vector is assumed to be Local (AV:L) based on the common use case of analyzing pcap files. If ssldump is deployed in a live-capture configuration where an attacker can inject crafted TLS traffic, the vector could be Network (AV:N).
- The 3-byte heap overflow is assumed to have the potential for code execution (VI:H, VA:H). In practice, a 3-byte overflow may more reliably cause a crash (DoS) than reliable code execution, but the worst-case impact is used for scoring.
- The CAPEC-109 mapping is the closest available pattern; no CAPEC specifically addresses heap buffer overflows caused by size miscalculation.
- No vendor, product version, or fixed version is specified in the patch metadata; these are marked as unknown/unspecified.
- The user interaction is classified as Active (UI:A) because the user must explicitly run ssldump on a crafted input file.

Title
Cisco SG350 and SG350X Series Managed Switches SNMP Denial of Service Vunerability
Summary
A vulnerability in the Simple Network Management Protocol (SNMP) subsystem of Cisco 350 Series Managed Switches (SG350) and Cisco 350X Series Stackable Managed Switches (SG350X) firmware could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
This vulnerability is due to improper error handling when parsing response data for a specific SNMP request. An attacker could exploit this vulnerability by sending a specific SNMP request to an affected device. A successful exploit could allow the attacker to cause the device to reload unexpectedly, resulting in a DoS condition.
This vulnerability affects SNMP versions 1, 2c, and 3. To exploit this vulnerability through SNMPv2c or earlier, the attacker must know a valid read-write or read-only SNMP community string for the affected system. To exploit this vulnerability through SNMPv3, the attacker must have valid SNMP user credentials for the affected system.

Mitigation
Pre-design: Use a language or compiler that performs automatic bounds checking.
Mitigation
Architecture and Design
Use an abstraction library to abstract away risky APIs. Not a complete solution.
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 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].
Mitigation
Implementation
Implement and perform bounds checking on input.
Mitigation
Implementation
Strategy: Libraries or Frameworks
Do not use dangerous functions such as gets. Look for their safe equivalent, which checks for the boundary.
Mitigation
Operation
Use OS-level preventative functionality. This is not a complete solution, but it provides some defense in depth.
CAPEC-92: Forced Integer Overflow
This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.
