Name of the Vulnerable Software and Affected Versions FreeRDP versions prior to 3.24.0

Description FreeRDP is a free implementation of the Remote Desktop Protocol. A flaw exists in the freerdp bitmap decompress planar function where an out-of-bounds read can occur when the SrcSize is 0. The function dereferences a pointer without verifying that SrcSize is greater than or equal to 1. When SrcSize is 0, reading from the source buffer can access memory beyond its boundaries.

Recommendations Update to version 3.24.0 or later.
