Description
This security bulletin contains information about 8 vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2026-111183)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the processing of RTP payload elements. A remote attacker can pass specially crafted data to the application, trigger a heap-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-2026-3083)
CWE-ID: CWE-787 - Out-of-bounds write
CVSSv4: 8.4 [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]
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error within the processing of X-QDM RTP payload elements. A remote attacker can trigger an out-of-bounds write and execute arbitrary code on the target system.
3) Heap-based buffer overflow (CVE-ID: CVE-2026-3085)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: 8.4 [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]
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the processing of X-QDM RTP payloads. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Heap-based buffer overflow (CVE-ID: CVE-2026-39043)
CWE-ID: CWE-122 - Heap-based Buffer Overflow
CVSSv4: 8.4 [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]
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.
5) Integer overflow (CVE-ID: CVE-2026-39044)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: 6.7 [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]
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.
6) Out-of-bounds read (CVE-ID: CVE-2026-46470)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 6.8 [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]
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.
7) Out-of-bounds read (CVE-ID: CVE-2026-46471)
CWE-ID: CWE-125 - Out-of-bounds read
CVSSv4: 4.6 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to disclose sensitive information or cause a denial of service.
The vulnerability exists due to out-of-bounds read in MP4 demuxer when handling specially crafted PlayReady DRM files. A remote attacker can supply a specially crafted file to disclose sensitive information or cause a denial of service.
User interaction is required to process a crafted media file.
8) Integer overflow (CVE-ID: CVE-2026-53705)
CWE-ID: CWE-190 - Integer overflow
CVSSv4: 6.7 [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]
The vulnerability allows a remote attacker to cause a denial of service.
The vulnerability exists due to integer overflow in the wavpackdec element when processing malformed WavPack audio files. A remote attacker can trick the victim into opening a crafted audio file to cause a denial of service.
