SUSE SLED15 / SLES15 Security Update : glib-networking (SUSE-SU-2021:3944-1)

medium Nessus Plugin ID 155898

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2021:3944-1 advisory.

- In GNOME glib-networking through 2.64.2, the implementation of GTlsClientConnection skips hostname verification of the server's TLS certificate if the application fails to specify the expected server identity. This is in contrast to its intended documented behavior, to fail the certificate verification.
Applications that fail to provide the server identity, including Balsa before 2.5.11 and 2.6.x before 2.6.1, accept a TLS certificate if the certificate is valid for any host. (CVE-2020-13645)

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 glib-networking and / or glib-networking-lang packages.
