Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
7) Out-of-bounds read (CVE-ID: CVE-2021-43804)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition when parsing RTCP BYE message. A remote attacker can trigger out-of-bounds read error and read contents of memory on the system.
8) Out-of-bounds read (CVE-ID: CVE-2021-43845)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within RTCP XR message. A remote attacker can trigger out-of-bounds read error and read contents of memory on the system.
9) Out-of-bounds read (CVE-ID: CVE-2022-21722)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition during RTP/RTCP parsing. A remote attacker can trigger out-of-bounds read error and read contents of memory on the system.
10) Out-of-bounds read (CVE-ID: CVE-2022-21723)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition during SIP message parsing. A remote attacker can trick the victim into opening it, trigger out-of-bounds read error and read contents of memory on the system.
11) Heap-based buffer overflow (CVE-ID: CVE-2022-23537)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when decoding STUN messages. A remote attacker can pass a specially crafted STUN message 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.
12) Heap-based buffer overflow (CVE-ID: CVE-2022-23547)
