CVE-2026-107736 (GCVE-0-2026-107736)

Title
SumatraPDF: stack buffer overflow while processing EXIF Orientation metadata
Summary
SumatraPDF is a multi-format reader for Windows. In 3.6.1 and earlier, MaybeFlipBitmap() asks GDI+ to read the attacker-controlled PropertyTagOrientation size through GetPropertyItem() while supplying only a fixed 64-byte buf on the stack. Opening a crafted TIFF with enough EXIF Orientation values can cause attacker-selected bytes to overwrite stack control data, while tested builds terminate through the stack cookie check. No broader impact is claimed beyond the advisory-supported conditions. No fixed version is available as of this review.

Title
Poppler 0.42.0 through 26.10.0 Stack Buffer Overflow via Decrypt::revision6Hash()
Summary
Poppler 0.42.0 through 26.10.0 contains a stack-based buffer overflow in Decrypt::revision6Hash() that allows attackers controlling the password to overwrite stack memory when opening AESV3/R6 encrypted PDFs. Attackers can supply a password longer than 127 bytes through applications using the libpoppler, libpoppler-glib or C++ API to overflow the K1 and E buffers, crashing the process or corrupting memory.

CVE-2026-105673 (GCVE-0-2026-105673)

Title
Unauthenticated RTSP Tunnel Denial-of-Service Vulnerability in TP-Link Tapo C325WB
Summary
An unauthenticated denial-of-service vulnerability exists in Tapo C325WB v2 in the RTSP streaming service on TCP port 554 when the Camera Account feature is enabled. A crafted pair of RTSP-over-HTTP tunneling requests can cause memory corruption and crash the streaming daemon.  Successful exploitation may allow an unauthenticated adjacent-network attacker to disrupt live video and related streaming functions until the affected service recovers or restarts.

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].
