CVE-2026-25941 FreeRDP: vuln_1_15_1 RDPGFX WIRE_TO_SURFACE_2 Out-of-Bounds Read

FreeRDP is a free implementation of the Remote Desktop Protocol. Versions on the 2.x branch prior to to 2.11.8 and on the 3.x branch prior to 3.23.0 have an out-of-bounds read vulnerability in the FreeRDP client's RDPGFX channel that allows a malicious RDP server to read uninitialized heap memory...

FreeRDP 安全漏洞

FreeRDP is an open-source RDP protocol implementation developed by the FreeRDP team. Versions of FreeRDP prior to 3.23.0 contained security vulnerabilities. These vulnerabilities stemmed from xfcliprdrprovidedata passing released pDstData to XChangeProperty, which could lead to reuse of a heap...

freerdp: FreeRDP heap-buffer-overflow

A heap based buffer overflow has been discovered in FreeRDP. In affected versions the URBDRC client does not perform bounds checking on server‑supplied MSUSBINTERFACEDESCRIPTOR values and uses them as indices in libusbudevcompletemsconfigsetup, causing an out‑of‑bounds read...

freerdp: FreeRDP: Heap buffer overflow via crafted RDPGFX surface updates leads to denial of service and potential code execution.

A flaw was found in FreeRDP. A malicious server can exploit an out-of-bounds read/write vulnerability in the ClearCodec component by sending crafted RDPGFX surface updates. This can trigger a client-side heap buffer overflow, leading to a crash Denial of Service DoS and potential heap corruption...
