Amazon Linux AMI : php54 (ALAS-2014-333)

medium Nessus Plugin ID 78276

Language:

Synopsis

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

Description

The BEGIN regular expression in the awk script detector in magic/Magdir/commands in file before 5.15 uses multiple wildcards with unlimited repetitions, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted ASCII file that triggers a large amount of backtracking, as demonstrated via a file with many newline characters.

Solution

Run 'yum update php54' to update your system.
