Beschreibung:	Summary: The remote host is missing an update for the 'pjproject' package(s) announced via the MGASA-2021-0337 advisory. Vulnerability Insight: Currently, PJSIP transport can be reused if they have the same IP address + port + protocol. However, this is insufficient for secure transport since it lacks remote hostname authentication. The vulnerability allows for an insecure interaction without user awareness. It affects users who need access to connections to different destinations that translate to the same address, and allows man-in-the-middle attack if attacker can route a connection to another destination such as in the case of DNS spoofing (CVE-2020-15260). An issue has been found in pjproject. Due to bad handling of two consecutive crafted answers to an INVITE, the attacker is able to crash the server resulting in a denial of service (CVE-2021-21375). Affected Software/OS: 'pjproject' package(s) on Mageia 8. Solution: Please install the updated package(s). CVSS Score: 4.3 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:N/A:P
