The vulnerability exists due to a boundary error within the ff_hevc_put_weighted_pred_avg_8_sse() function in sse-motion.cc. A remote attacker pass a specially crafted video file to the application, trigger an out-of-bounds write and perform a denial of service (DoS) attack.

6) Reachable Assertion (CVE-ID: CVE-2021-36409)

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

The vulnerability exists due to a reachable assertion in sps.cc. A remote attacker can pass a specially crafted file to the application and crash it.


7) Out-of-bounds write (CVE-ID: CVE-2022-43242)

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

The vulnerability exists due to a boundary error within the mc_luma() function in motion.cc. A remote attacker pass a specially crafted video file to the application, trigger an out-of-bounds write and perform a denial of service (DoS) attack.


8) Input validation error (CVE-ID: CVE-2022-43241)

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

The vulnerability exists due to insufficient validation of user-supplied input within the ff_hevc_put_hevc_qpel_v_3_8_sse() function in sse-motion.cc. A remote attacker can pass specially crafted video file to the application and perform a denial of service (DoS) attack.


9) Input validation error (CVE-ID: CVE-2022-43238)

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

The vulnerability exists due to insufficient validation of user-supplied input within the ff_hevc_put_hevc_qpel_h_3_v_3_sse() function in sse-motion.cc. A remote attacker can pass specially crafted video input to the application and perform a denial of service (DoS) attack.


10) Out-of-bounds read (CVE-ID: CVE-2021-36411)

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

The vulnerability exists due to a boundary condition within the derive_boundaryStrength() function in deblock.cc. A remote attacker can pass a specially crafted file to the application, trigger an out-of-bounds read error and perform a denial of service (DoS) attack.

11) Out-of-bounds read (CVE-ID: CVE-2021-35452)

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

The vulnerability exists due to a boundary condition in slice.cc. A remote attacker can pass a specially crafted file to the application, trigger an out-of-bounds read error and perform a denial of service (DoS) attack.


12) Heap-based buffer overflow (CVE-ID: CVE-2022-1253)

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

The vulnerability exists due to a boundary error within the read_sps_NAL() function in decctx.cc. A remote attacker can pass specially crafted video 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.
