 It was found that libde265, an open source implementation of the H.265 video codec, had multiple vulnerabilities which could lead to both stack and heap out of bound writes that could lead to denial of service, etc.

 For Debian 11 bullseye, these problems have been fixed in version 1.0.11-0+deb11u4.

 We recommend that you upgrade your libde265 packages.
