Doc Text:
A flaw was found in FreeRDP. This flaw allows arbitrary code execution or a Denial of Service (DoS) when parsing persistent cache files. A local attacker can trigger this vulnerability by tricking a user into loading a maliciously crafted cache file containing oversized image dimensions. This manipulation leads to an integer calculation error and a heap-based buffer overflow, causing memory corruption.

Description OSIDB Bzimport 2026-10-16 01:42:01 UTC 
FreeRDP before 3.32.0 contains a heap buffer overflow vulnerability in persistent_cache_read_entry_v2 that allows local attackers to corrupt heap memory via integer wraparound in bitmap size calculation. Attackers can craft a persistent cache v2 file with oversized width and height values that causes mismatched entry size accounting and fixed 16 KiB reads, leading to crashes or code execution when loaded.
