Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES15 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2020:0948-2 advisory.

- GnuTLS 3.6.x before 3.6.13 uses incorrect cryptography for DTLS. The earliest affected version is 3.6.3 (2018-07-16) because of an error in a 2017-10-06 commit. The DTLS client always uses 32 '\0' bytes instead of a random value, and thus contributes no randomness to a DTLS negotiation. This breaks the security guarantees of the DTLS protocol. (CVE-2020-11501)

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

Solution

Update the affected packages.
