Description

This security bulletin contains information about 3 vulnerabilities.


1) Stack-based buffer overflow (CVE-ID: CVE-2026-5056)

CWE-ID: CWE-121 - Stack-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 on the target system.

The vulnerability exists due to a boundary error within the parsing of UncompressedFrameConfigBox structures in the qtdemux element. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) 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.


3) 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.
