CVE-2026-66040 FFmpeg Heap Out-of-Bounds Write via PNG/APNG eXIf Encoder

FFmpeg through 8.1.2, fixed in commit b506faf, contains a heap out-of-bounds write vulnerability in the native PNG and APNG encoders that allows remote attackers to corrupt heap memory by supplying a crafted PNG image with a malicious eXIf chunk. Attackers can craft an eXIf chunk where multiple I...

CVE-2026-66039

FFmpeg through 8.1.2, fixed in commit aafb5c6, contains a signed integer overflow vulnerability in the MACE6 audio decoder that allows attackers to corrupt heap memory by supplying a crafted CAF file with a malicious bytesperpacket value. Attackers can craft a CAF file with oversized bytesperpack...

CVE-2026-66038 FFmpeg LCL/ZLIB Video Decoder Information Disclosure via lcldec.c

FFmpeg through 8.1.2, fixed in commit 8670835, contains an information disclosure vulnerability in the LCL/ZLIB video decoder that allows attackers to expose uninitialized heap memory by supplying a valid zlib stream that inflates to fewer bytes than the expected frame size. The zlibdecomp functi...

CVE-2026-65706

A flaw was found in FFmpeg. This vulnerability, an out-of-bounds write in the vfswaprect video filter, allows an attacker to corrupt heap memory. By providing a specially crafted NV12 video frame with specific dimensions, a local user can trigger a memory corruption, leading to a process crash...

CVE-2026-65704

FFmpeg through 8.1.2 contains an out-of-bounds write vulnerability that allows attackers to cause heap corruption by supplying a crafted ffconcat file processed with the -safe 0 flag. The TY demuxer's demuxaudio function decrements packet size without bounds checking, producing a negative size...

UBUNTU-CVE-2026-65705

FFmpeg versions 3.4 through 8.1.2 contain an out-of-bounds write vulnerability in the vffloodfill video filter that allows attackers to corrupt heap memory by supplying a dynamically sized video stream with filtergraph reinitialization disabled via -reinitfilter 0. When configinput allocates the...

CVE-2026-65706

FFmpeg versions 3.0 through 8.1.2 contain an out-of-bounds write vulnerability in the vfswaprect video filter that allows attackers to corrupt heap memory by supplying a crafted NV12 video frame with odd width dimensions. The filterframe function reuses a temporary row buffer sized for plane 0's...

CVE-2026-65704

CVE-2026-65704 affects FFmpeg up to version 8.1.2, where the TY demuxer’s demux_audio() decrements packet size without bounds checking, producing a negative size that, when passed to memcpy in shorten_decode_frame(), wraps to near SIZE_MAX and causes heap corruption from reads beyond the source a...

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...

CVE-2026-64833

FFmpeg versions 0.7.1 through 8.1.2 contain an out-of-bounds read vulnerability in the S/PDIF muxer that allows attackers to access memory beyond buffer boundaries by supplying a crafted DTS stream with a coresize value larger than the actual packet length. Attackers can exploit the missing bound...

CVE-2026-64833

FFmpeg versions 0.7.1–8.1.2 expose an out-of-bounds read in the S/PDIF muxer. The root cause is a missing bounds check in spdif_header_dts4, allowing a crafted DTS stream with core_size larger than the packet length to read memory beyond the packet buffer during S/PDIF re-muxing. As described, th...
