Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Out-of-bounds write (CVE-ID: CVE-2023-49468)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error within the read_coding_unit() function in slice.cc. A remote attacker can pass specially crafted input to the application, trigger an out-of-bounds write and execute arbitrary code on the target system.
2) Heap-based buffer overflow (CVE-ID: CVE-2023-49467)
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_combined_bipredictive_merging_candidates() function in motion.cc. A remote attacker can pass specially crafted data 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.
3) Heap-based buffer overflow (CVE-ID: CVE-2023-49465)
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 data 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.
