CVE-2026-44988 LibVNCClient Tight Gradient decoding allows malicious server-triggered heap/stack OOB writes
LibVNCClient is a library for easy implementation of a VNC client. In 0.9.15 and earlier, LibVNCClient's Tight encoding decoder uses fixed-size 2048-pixel scratch buffers for the Gradient filter, but it does not reject Tight rectangles whose width is larger than 2048 pixels. A malicious VNC serve...
UBUNTU-CVE-2026-40033
FreeRDP before 3.26.0 contains a heap-buffer-overflow vulnerability in gdiCacheToSurface that allows remote attackers to write out-of-bounds heap memory. The vulnerability occurs because rectangle validation clamps coordinates to UINT16MAX but performs copy operations using unclamped cache entry...

CVE-2026-40033
FreeRDP before 3.26.0 is affected by a heap-buffer-overflow in gdi_CacheToSurface. The issue stems from rectangle validation clamping coordinates to UINT16_MAX while copy operations use unclamped cache entry dimensions, enabling a malicious RDP server to trigger large out-of-bounds writes and pot...

CVE-2026-23531
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, in ClearCodec, when glyphData is present, cleardecompress calls freerdpimagecopynooverlap without validating the destination rectangle, allowing an out-of-bounds read/write via crafted RDPGFX surface updates...
FreeRDP security vulnerabilities
FreeRDP is an open-source RDP protocol implementation developed by the FreeRDP team. Versions of FreeRDP prior to 3.21.0 contained security vulnerabilities. These vulnerabilities stemmed from the cleardecompress function in ClearCodec, which did not validate the target rectangle, potentially...
