CVSS v3.1

9.8

Critical

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions FreeRDP versions prior to 3.20.1

Description A malicious RDP server can cause a heap-buffer-overflow write in the FreeRDP client when processing Audio Input (AUDIN) format lists. The audin process formats function reuses the callback->formats count variable across multiple MSG SNDIN FORMATS Protocol Data Units (PDUs), leading to a write beyond the bounds of the newly allocated formats array and resulting in memory corruption and a crash.

Recommendations Update to version 3.20.1 or later.
