Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) 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.


2) Use-after-free (CVE-ID: CVE-2022-23608)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in dialog set. A remote attacker can send a specially crafted request to cause a dialog set to be registered in the hash table multiple times and results in an endless loop condition.


3) 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.


4) 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.


5) 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.


6) Input validation error (CVE-ID: CVE-2021-41141)

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

The vulnerability exists due to the missing of unreleased locks in failure cases. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


7) Integer overflow (CVE-ID: CVE-2021-37706)

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

The vulnerability exists due to integer overflow within STUN message that contains an ERROR-CODE attribute. A remote attacker can pass specially crafted data to the application, trigger integer overflow and execute arbitrary code on the target system.

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