                     CVE-2026-42225


    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.

    For the detailed security status of asterisk please refer to
    its security tracker page at:
