Amazon Linux 2 : glib2 (ALAS-2024-2519)

high Nessus Plugin ID 193528

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 ALAS2-2024-2519 advisory.

 - GNOME GLib before 2.65.3 has an integer overflow, that might lead to an out-of-bounds write, in g_option_group_add_entries. NOTE: the vendor's position is Realistically this is not a security issue.
 The standard pattern is for callers to provide a static list of option entries in a fixed number of calls to g_option_group_add_entries(). The researcher states that this pattern is undocumented (CVE-2020-35457)

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.
