Description

This security bulletin contains information about 8 secuirty vulnerabilities.

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

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)

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.

3) NULL pointer dereference (CVE-ID: CVE-2023-24756)

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_unweighted_pred_8_sse() function in sse-motion.cc. A remote attacker can trigger denial of service conditions via a crafted video file.

4) NULL pointer dereference (CVE-ID: CVE-2023-24755)

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_weighted_pred_8_fallback() function at fallback-motion.cc. A remote attacker can trigger denial of service conditions via a crafted video file.

5) NULL pointer dereference (CVE-ID: CVE-2023-24754)

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 at sse-motion.cc. A remote attacker can trigger denial of service conditions via a crafted video file.

6) NULL pointer dereference (CVE-ID: CVE-2023-24752)

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_hevc_epel_pixels_8_sse() function at sse-motion.cc. A remote attacker can trigger denial of service conditions via a crafted video file.

7) NULL pointer dereference (CVE-ID: CVE-2023-24751)

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 mc_chroma() function at motion.cc. A remote attacker can pass a specially crafted file to the application and crash it.

8) Heap-based buffer overflow (CVE-ID: CVE-2023-25221)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the derive_spatial_luma_vector_prediction() function in motion.cc. A remote attacker can pass specially crafted file 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.
