Amazon Linux AMI : libxslt (ALAS-2019-1241)

critical Nessus Plugin ID 127069
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

libxslt allows bypass of a protection mechanism because callers of xsltCheckRead and xsltCheckWrite permit access even upon receiving a
-1 error code. xsltCheckRead can return -1 for a crafted URL that is not actually invalid and is subsequently loaded. (CVE-2019-11068)

Solution

Run 'yum update libxslt' to update your system.
