Debian Security Advisory DSA-5203-1 security@debian.org

August 08, 2022 https://www.debian.org/security/faq

Package : gnutls28
CVE ID : CVE-2022-2509
Jaak Ristioja discovered a double-free vulnerability in GnuTLS, a
library implementing the TLS and SSL protocols, during verification of
pkcs7 signatures. A remote attacker can take advantage of this flaw to
cause an application using the GnuTLS library to crash (denial of
service), or potentially, to execute arbitrary code.
For the stable distribution (bullseye), this problem has been fixed in
version 3.7.1-5+deb11u2.
We recommend that you upgrade your gnutls28 packages.
For the detailed security status of gnutls28 please refer to its
security tracker page at:
https://security-tracker.debian.org/tracker/gnutls28
