- FFmpeg 7.0+ Integer Overflow in FFmpeg cache: Protocol (CacheEntry::size) September 8, 2025Posted by Ron E on Sep 08An integer overflow vulnerability exists in the FFmpeg cache: URL protocol implementation. The CacheEntry structure uses a 32-bit signed integer to store cache entry sizes (int size), but the cache layer can accumulate cached data exceeding 2 GB. Once entry->size grows beyond INT_MAX and new data is appended, an […]
- FFmpeg 7.0+ Integer Overflow in DSCP Option Handling of FFmpeg UDP Protocol September 8, 2025Posted by Ron E on Sep 08A vulnerability exists in the FFmpeg UDP protocol implementation ( libavformat/udp.c) where the dscp parameter is parsed from a URI and left-shifted without bounds checking. Supplying a maximum 32-bit signed integer (2147483647) triggers undefined behavior due to a left shift that exceeds the representable range of int. This results […]
