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

High Nessus Plugin ID 127069

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.
