Amazon Linux AMI : glib2 (ALAS-2023-1769)

critical Nessus Plugin ID 177376

Language:

Synopsis

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

Description

The version of glib2 installed on the remote host is prior to 2.36.3-5.25. It is, therefore, affected by a vulnerability as referenced in the ALAS-2023-1769 advisory.

PCRE before 8.38 mishandles the interaction of lookbehind assertions and mutually recursive subpatterns, which allows remote attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror. (CVE-2015-8386)

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.
