FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based based clients using /bpp:32 legacy GDI drawing path with a version of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to out-of-bounds read. Versions 3.5.0 and 2.11.6 patch the issue. As a workaround, use modern drawing paths (e.g. /rfx or /gfx options). The workaround requires server side support.
AnalysisAI
FreeRDP is a free implementation of the Remote Desktop Protocol. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Read (CWE-125), which allows attackers to read data from memory outside the intended buffer boundaries. FreeRDP is a free implementation of the Remote Desktop Protocol. FreeRDP based based clients using /bpp:32 legacy GDI drawing path with a version of FreeRDP prior to 3.5.0 or 2.11.6 are vulnerable to out-of-bounds read. Versions 3.5.0 and 2.11.6 patch the issue. As a workaround, use modern drawing paths (e.g. /rfx or /gfx options). The workaround requires server side support. Affected products include: Freerdp, Fedoraproject Fedora. Version information: prior to 3.5.0.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate array indices and buffer lengths. Use memory-safe languages. Enable AddressSanitizer during testing.
