freerdp: FreeRDP global-buffer-overflow

A global buffer overflow flaw has been discovered in FreeRDP. This global-buffer-overflow was observed in FreeRDP's Base64 decoding path. The root cause appears to be implementation-defined char signedness: on Arm/AArch64 builds, plain char is treated as unsigned, so the guard c = 0 can be...

CVE-2026-29612

OpenClaw versions prior to 2026.2.14 decode base64-backed media inputs into buffers before enforcing decoded-size budget limits, allowing attackers to trigger large memory allocations. Remote attackers can supply oversized base64 payloads to cause memory pressure and denial of service...

Allocation of Resources Without Limits or Throttling

Overview openclaw is a 🦞 OpenClaw — Personal AI Assistant Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the base64 media decoding. An attacker can exhaust system memory resources by submitting oversized base64-encoded payloads, leadin...

Medium: freerdp

Issue Overview: FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, a race condition between the RDPGFX dynamic virtual channel thread and the SDL render thread leads to a heap use-after-free. Specifically, an escaped pointer to sdl-primary SDLSurface is accessed aft...

CVE-2026-2016

A security vulnerability has been detected in happyfish100 libfastcommon up to 1.0.84. Affected by this vulnerability is the function base64decode of the file src/base64.c. The manipulation leads to stack-based buffer overflow. Local access is required to approach this attack. The exploit has bee...

CVE-2020-37124

B64dec 1.1.2 contains a buffer overflow vulnerability that allows attackers to execute arbitrary code by overwriting Structured Exception Handler SEH with crafted input. Attackers can leverage an egg hunter technique and carefully constructed payload to inject and execute malicious code during...
