Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop through the rtpasffixheader function in libavformat/rtpdecasf.c. An attacker can exhaust CPU and prevent normal service by sending a crafted RTP/ASF stream containing ASF objects with a chunksize smaller than the 24-byte...

Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write in adxdecodeframe in libavcodec/adxdec.c. An attacker can trigger memory corruption or a crash by supplying a crafted ADX or AAX audio stream that delivers AVPKTDATANEWEXTRADATA mid-stream and changes the channel...

Double Free

Overview Affected versions of this package are vulnerable to Double Free in ffnvdecstartframesepref in libavcodec/nvdec.c. An attacker can corrupt memory by supplying a crafted video file that drives NVDEC decoding into the “No decoder surfaces left” error path, where the frame-description contex...

Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read through the spdifheaderdts4 function in libavformat/spdifenc.c. An attacker can read memory beyond the packet buffer by supplying a crafted DTS-HD stream with a coresize value larger than the actual packet length duri...

FFmpeg: FFmpeg: Memory corruption via crafted RASC video stream

A flaw was found in FFmpeg's RASC video decoder. A remote attacker could exploit this by providing a crafted media stream using the RASC FourCC Four Character Code, which is then decoded by libavcodec. This vulnerability triggers a bitstream-controlled out-of-bounds heap write and an adjacent...
