Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 11 / 12 host has packages installed that are affected by a vulnerability as referenced in the dsa-5472 advisory.

It was discovered that an incorrect implementation of AES GCM decryption in cjose, a C library implementing the JOSE standard, may allow an attacker to provide a truncated Authentication Tag and modify the JWE object. For the oldstable distribution (bullseye), this problem has been fixed in version 0.6.1+dfsg1-1+deb11u1. For the stable distribution (bookworm), this problem has been fixed in version 0.6.2.1-1+deb12u1. We recommend that you upgrade your cjose packages. For the detailed security status of cjose please refer to its security tracker page at: https://security-tracker.debian.org/tracker/cjose

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the cjose packages.

For the stable distribution (bookworm), this problem has been fixed in version 0.6.2.1-1+deb12u1.
