Rocky Linux 8 : glib2 (RLSA-2021:4385)

medium Nessus Plugin ID 184548

Synopsis

The remote Rocky Linux host is missing one or more security updates.

Description

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:4385 advisory.

 - An issue was discovered in GNOME GLib before 2.66.8. When g_file_replace() is used with G_FILE_CREATE_REPLACE_DESTINATION to replace a path that is a dangling symlink, it incorrectly also creates the target of the symlink as an empty file, which could conceivably have security relevance if the symlink is attacker-controlled. (If the path is a symlink to a file that already exists, then the contents of that file correctly remain unchanged.) (CVE-2021-28153)

 - A flaw was found in glib before version 2.63.6. Due to random charset alias, pkexec can leak content from files owned by privileged users to unprivileged ones under the right condition. (CVE-2021-3800)

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

Solution

Update the affected packages.
