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.
