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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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.
