Amazon Linux 2 : glib2 (ALAS-2021-1711)

high Nessus Plugin ID 153898

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 ALAS2-2021-1711 advisory.

An issue was discovered in GNOME GLib before 2.66.7 and 2.67.x before 2.67.4. If g_byte_array_new_take() was called with a buffer of 4GB or more on a 64-bit platform, the length would be truncated modulo 2**32, causing unintended length truncation. (CVE-2021-27218)

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.
