Denial of service via clip-action memory leaks
Published Feb 20, 2025 · Updated Feb 20, 2025
Memory leaks in libming 0.4.8 clip-action parsing allow remote attackers to interrupt service by supplying a crafted SWF file. parseSWF_CLIPACTIONS and parseSWF_CLIPACTIONRECORD allocate and repeatedly expand ClipActionRecords and Actions arrays without releasing the resulting heap allocations. Exploitation requires a target process or user to parse the attacker-supplied file; the bounded consequence is availability loss from exhausted memory.
