Description

This security bulletin contains information about 8 vulnerabilities.


1) NULL pointer dereference (CVE-ID: CVE-2023-24758)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error within the ff_hevc_put_weighted_pred_avg_8_sse() function in sse-motion.cc. A remote attacker can trigger denial of service conditions via a crafted video file.


2) NULL pointer dereference (CVE-ID: CVE-2023-24757)

CWE-ID: CWE-476 - NULL Pointer Dereference

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error within the put_unweighted_pred_16_fallback() function in fallback-motion.cc. A remote attacker can trigger denial of service conditions via a crafted video file.
