Amazon Linux AMI : glib2 (ALAS-2023-1775)

critical Nessus Plugin ID 177907

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 2.36.3-5.26. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1775 advisory.

- Heap-based buffer overflow in the find_fixedlength function in pcre_compile.c in PCRE before 8.38 allows remote attackers to cause a denial of service (crash) or obtain sensitive information from heap memory and possibly bypass the ASLR protection mechanism via a crafted regular expression with an excess closing parenthesis. (CVE-2015-5073)

- 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)

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.
