When FreeRDP loads a persistent cache file, an integer wraparound in the size calculation in persist_cache_get_data, triggered by large attacker-controlled width and height values in a crafted v3 persistent cache file, causes an undersized buffer to be allocated, which is then overflowed when the entry is read in persistent_cache_read_entry_v3. A local attacker who can place a crafted persistent cache file and have it loaded by a user could use this flaw to crash the FreeRDP client or potentially execute arbitrary code in the context of the client process. The freerdp component is affected as shipped in multiple Red Hat Enterprise Linux versions, in Red Hat In-Vehicle OS, and in the Fedora and EPEL community streams, where a fix is being pursued; the Red Hat Enterprise Linux 6 Extended Lifecycle Support stream is out of support scope. Red Hat rates this flaw as IMPORTANT with a CVSS 3.1 score of 7.3, consistent with the upstream severity assessment.", "threat_severity": "Important"}
