The remote Debian 12 host has packages installed that are affected by a vulnerability as referenced in the dsa-5764 advisory.
- ------------------------------------------------------------------------- Debian Security Advisory DSA-5764-1 [email protected] https://www.debian.org/security/ Salvatore Bonaccorso September 03, 2024 https://www.debian.org/security/faq
- -------------------------------------------------------------------------
Package : openssl CVE ID : CVE-2024-6119
David Benjamin reported a flaw in the X.509 name checks in OpenSSL, a Secure Sockets Layer toolkit, which may cause an application performing certificate name checks to crash, resulting in denial of service.
Additional details can be found in the upstream advisory:
https://openssl-library.org/news/secadv/20240903.txt
For the stable distribution (bookworm), this problem has been fixed in version 3.0.14-1~deb12u2.
We recommend that you upgrade your openssl packages.
For the detailed security status of openssl please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/openssl
