Amazon Linux 2 : glib2 (ALAS-2024-2487)

medium Nessus Plugin ID 191525

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of glib2 installed on the remote host is prior to 2.56.1-9. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2487 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)

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

Solution

Run 'yum update glib2' to update your system.
