FreeBSD : lizard -- Negative size passed to memcpy resulting in memory corruption (67c2eb06-5579-4595-801b-30355be24654)

high Nessus Plugin ID 189901

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 67c2eb06-5579-4595-801b-30355be24654 advisory.

 - In Lizard v1.0 and LZ5 v2.0 (the prior release, before the product was renamed), there is an unchecked buffer size during a memcpy in the Lizard_decompress_LIZv1 function (lib/lizard_decompress_liz.h). Remote attackers can leverage this vulnerability to cause a denial of service via a crafted input file, as well as achieve remote code execution. (CVE-2018-11498)

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

Solution

Update the affected packages.
