Description

This security bulletin contains information about 4 secuirty vulnerabilities.

1) Unchecked return value (CVE-ID: CVE-2021-38171)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to an unchecked return value within the adts_decode_extradata() function in libavformat/adtsenc.c. A remote attacker can trick the victim to open a specially crafted image and execute arbitrary code on the system.

2) NULL pointer dereference (CVE-ID: CVE-2022-3109)

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 vp3_decode_frame() function in libavcodec/vp3.c in FFmpeg. A remote attacker can perform a denial of service (DoS) attack.

3) Buffer overflow (CVE-ID: CVE-2023-50010)

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

The vulnerability exists due to a boundary error within the set_encoder_id() function in /fftools/ffmpeg_enc.c A remote attacker can pass specially crafted input to the application, trigger memory corruption and execute arbitrary code on the target system.

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

4) Buffer overflow (CVE-ID: CVE-2023-51793)

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

The vulnerability exists due to a boundary error in image_copy_plane() function in libavutil/imgutils.c. A remote attacker can pass specially crafted input to the application, trigger memory corruption and execute arbitrary code on the target system.

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