Amazon Linux 2 : libpng (ALAS-2023-1904)

high Nessus Plugin ID 170440

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of libpng installed on the remote host is prior to 1.5.13-8. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-1904 advisory.

 - Integer underflow in the png_check_keyword function in pngwutil.c in libpng 0.90 through 0.99, 1.0.x before 1.0.66, 1.1.x and 1.2.x before 1.2.56, 1.3.x and 1.4.x before 1.4.19, and 1.5.x before 1.5.26 allows remote attackers to have unspecified impact via a space character as a keyword in a PNG image, which triggers an out-of-bounds read. (CVE-2015-8540)

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 libpng' to update your system.
