Amazon Linux 2 : glib2 (ALAS-2023-2107)

critical Nessus Plugin ID 177866

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 multiple vulnerabilities as referenced in the ALAS2-2023-2107 advisory.

PCRE before 8.38 mishandles the [: and \ substrings in character classes, which allows remote attackers to cause a denial of service (uninitialized memory read) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.
(CVE-2015-8390)

PCRE before 8.38 mishandles the (?(<digits>) and (?(R<digits>) conditions, which allows remote attackers to cause a denial of service (integer overflow) or possibly have unspecified other impact via a crafted regular expression, as demonstrated by a JavaScript RegExp object encountered by Konqueror.
(CVE-2015-8394)

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

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

Solution

Run 'yum update glib2' to update your system.
