Description Srikanth Balasubramanian 2026-10-28 06:59:52 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

FreeRDP 3.11.0 before 3.32.0 does not validate that AVC444 and AVC444v2 region widths are even before YUV444 conversion, so an odd width reaches an assertion and aborts the client. A malicious or compromised RDP server can terminate a connected FreeRDP client after RDPGFX AVC444 negotiation by sending an in-bounds region rectangle with an odd width.

Comment 1 Ondrej Holy 2026-11-02 15:10:16 UTC
Fixed in FreeRDP 3.32.0 (upstream). Fedora 43, 44, 45 and Rawhide ship freerdp 3.32.2, which contains the fix. Closing as ERRATA.
