Description

This security bulletin contains information about 5 secuirty vulnerabilities.

1) Use-after-free (CVE-ID: CVE-2022-48434)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in libavcodec/pthread_frame.c. A remote attacker can pass a specially crafted file to the application, trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

2) 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.

3) 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.

4) Heap-based buffer overflow (CVE-ID: CVE-2023-51794)

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

The vulnerability exists due to a boundary error in libavfilter/af_stereowiden.c. A remote attacker can pass specially crafted media 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.

5) Buffer overflow (CVE-ID: CVE-2023-51798)

The vulnerability allows a remote attacker to crash the application.

The vulnerability exists due to a boundary error in libavfilter/vf_minterpolate.c. A remote attacker can pass specially crafted input to the application, trigger memory corruption and perform a denial of service (DoS) attack.
