Multiple security vulnerabilities have been identified in FFmpeg versions prior to 6.1.1-54.oe2403sp4. These include a stack exhaustion vulnerability in the MOV demuxer that can cause process crashes and high CPU usage, as well as several use of uninitialized variable or resource vulnerabilities in various decoders (Go2Meeting, PCX, Sun Raster, CDXL, Huffyuv) that can lead to memory leaks exposing stack or heap contents. These issues affect versions up to 9.0.2 and earlier, depending on the specific vulnerability. A fix is available in version 6.1.1-54.oe2403sp4.
