Description
This security bulletin contains information about 5 vulnerabilities.
1) Out-of-bounds write (CVE-ID: CVE-2026-46469)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to out-of-bounds read and out-of-bounds write in the MOV/MP4 demuxer audio channel layout parsing code when parsing crafted chan and chnl boxes with more than 63 audio channels. A remote attacker can supply a specially crafted media file to cause a denial of service.
Successful exploitation may also disclose sensitive information through out-of-bounds reads.
2) Out-of-bounds read (CVE-ID: CVE-2026-46470)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to out-of-bounds read in the MOV/MP4 demuxer audio channel layout parsing code when parsing a crafted file that uses an invalid defined layout index. A remote attacker can supply a specially crafted media file to cause a denial of service.
Successful exploitation may also disclose sensitive information through out-of-bounds reads.
3) Division by zero (CVE-ID: CVE-2026-46472)
CWE-ID: CWE-369 - Divide By Zero
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to division by zero in the MOV/MP4 demuxer audio channel layout parsing code when parsing a crafted file that signals zero audio channels. A remote attacker can supply a specially crafted media file to cause a denial of service.
User interaction is required to open or process a crafted media file.
4) Integer overflow (CVE-ID: CVE-2026-39044)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to integer overflow in the WAV parser (wavparse) when parsing malformed WAV files with cue chunks. A remote attacker can trick the victim into opening a crafted WAV file to cause a denial of service.
Memory exhaustion may also occur during cue chunk parsing.
5) Heap-based buffer overflow (CVE-ID: CVE-2026-39043)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code.
The vulnerability exists due to a heap-based buffer overflow in the Matroska demuxer when parsing a crafted Matroska file with bz2-compressed tracks. A remote attacker can provide a specially crafted Matroska file to execute arbitrary code.
The issue can also cause an application crash.
