Multiple security vulnerabilities have been discovered in Asterisk, an Open
Source Private Branch Exchange. Buffer overflows and other programming errorscould be exploited for launching a denial of service attack or the execution of
arbitrary code.

For the stable distribution (bullseye), these problems have been fixed in
