Package : asterisk Version : 1:16.28.0~dfsg-0+deb10u1 CVE ID : CVE-2021-37706 CVE-2021-43299 CVE-2021-43300 CVE-2021-43301 CVE-2021-43302 CVE-2021-43303 CVE-2021-43804 CVE-2021-43845 CVE-2021-46837 CVE-2022-21722 CVE-2022-21723 CVE-2022-23608 CVE-2022-24763 CVE-2022-24764 CVE-2022-24786 CVE-2022-24792 CVE-2022-24793 CVE-2022-26498 CVE-2022-26499 CVE-2022-26651 Debian Bug : 1014998 1018073 1014976

Multiple security vulnerabilities have been found in Asterisk, an Open Source Private Branch Exchange. Buffer overflows and other programming errors could be exploited for information disclosure or the execution of arbitrary code.

Special care should be taken when upgrading to this new upstream release.
Some configuration files and options have changed in order to remedy certain security vulnerabilities. Most notably the pjsip TLS listener only accepts TLSv1.3 connections in the default configuration now. This can be reverted by adding method=tlsv1_2 to the transport in pjsip.conf. See also https://issues.asterisk.org/jira/browse/ASTERISK-29017.

For Debian 10 buster, these problems have been fixed in version 1:16.28.0~dfsg-0+deb10u1.

We recommend that you upgrade your asterisk packages.
