Amazon Linux 2 : libwmf (ALAS-2020-1533)

critical Nessus Plugin ID 141976

Language:

Synopsis

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

Description

The version of libwmf installed on the remote host is prior to 0.2.8.4-44. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2020-1533 advisory.

The GD Graphics Library (aka LibGD) 2.2.5 has a double free in the gdImage*Ptr() functions in gd_gif_out.c, gd_jpeg.c, and gd_wbmp.c. NOTE: PHP is unaffected. (CVE-2019-6978)

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 libwmf' to update your system.
