Doc Text:
A flaw was found in FreeRDP. This vulnerability allows a local attacker to execute arbitrary code or cause a denial of service (DoS) by supplying a specially crafted persistent cache file. When processing the malformed cache file, an arithmetic calculation error causes an undersized memory buffer to be allocated, leading to a heap-based buffer overflow during data read operations.

Description OSIDB Bzimport 2026-10-16 01:41:39 UTC 
FreeRDP before 3.32.0 contains a heap buffer overflow vulnerability in persistent_cache_read_entry_v3 that allows local attackers to corrupt memory by supplying a crafted v3 persistent cache file. Attackers can set large width and height values that wrap the size calculation in persist_cache_get_data, causing fread to overflow an undersized buffer and potentially execute code.
