high Nessus Plugin ID 144807

Language:

Synopsis

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

Description

The version of gd installed on the remote host is prior to 2.0.35-27. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1577 advisory.

 An integer overflow, leading to a heap-based buffer overflow was found in the imagecreatefromgd2() function of PHP's gd extension. A remote attacker could use this flaw to crash a PHP application or execute arbitrary code with the privileges of the user running that PHP application, using gd via a specially crafted GD2 image. (CVE-2016-5766)

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 gd' to update your system.
