Amazon Linux AMI : graphviz (ALAS-2021-1513)

high Nessus Plugin ID 151519

Language:

Synopsis

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

Description

The version of graphviz installed on the remote host is prior to 2.38.0-18.52. It is, therefore, affected by a vulnerability as referenced in the ALAS-2021-1513 advisory.

 A flaw was found in graphviz. A wrong assumption in record_init function leads to an off-by-one write in parse_reclbl function, allowing an attacker who can provide graph input to potentially execute code when the label of a node is invalid and shorter than two characters. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-18032)

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 graphviz' to update your system.
