 Several issues have been found in asterisk, an Open Source Private Branch Exchange (PBX). They are related to buffer under- or overflows, either on heap or on stack. Some are related to use-after-free or wrong processing of invalid or untrusted certificates.



 For Debian 11 bullseye, these problems have been fixed in version 1:16.28.0~dfsg-0+deb11u10.

 We recommend that you upgrade your asterisk packages.
