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...

CVE-2020-37124

CVE-2020-37124 affects B64dec 1.1.2. The vulnerability is a buffer overflow that allows arbitrary code execution by overwriting the Structured Exception Handler (SEH) with crafted input during the base64 decoding process. An egg-hunter technique and a carefully constructed payload are described a...

CVE-2025-12781

When passing data to the b64decode, standardb64decode, and urlsafeb64decode functions in the "base64" module the characters "+/" will always be accepted, regardless of the value of "altchars" parameter, typically used to establish an "alternative base64 alphabet" such as the URL safe alphabet. Th...

CVE-2025-59355

A vulnerability. When org.apache.linkis.metadata.util.HiveUtils.decode fails to perform Base64 decoding, it records the complete input parameter string in the log via logger.errorstr + "decode failed", e. If the input parameter contains sensitive information such as Hive Metastore keys, plaintext...

CVE-2025-59355

Apache Linkis CVE-2025-59355 affects 1.0.0–1.7.0, where HiveUtils.decode() may log the full input parameter on Base64 decode failure, risking leakage of sensitive values (e.g., hive-site.xml passwords) if error logs are readable. A fix is available in 1.8.0+ that desensitizes the log (logger.erro...

SUSE CVE-2026-22858

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.20.1, 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 = ...

CVE-2026-22775

Summary : CVE-2026-22775 affects the Svelte devalue library. Vulnerable range : devalue.parse input handling from versions 5.1.0 through 5.6.1. Root cause : the ArrayBuffer hydration path decodes input as base64 without validating the input first, allowing crafted data to cause excessive CPU time...
