AIX Perl Advisory : perl_advisory4.asc

high Nessus Plugin ID 73735

Language:

Synopsis

The remote AIX host has a vulnerable version of Perl.

Description

The version of Perl on the remote host is affected by a code execution vulnerability.

The _compile function in Locale::Maketext in Perl before 5.17.7 does not properly handle backslashes and fully qualified method names during compilation of bracket notation. This could allow context- dependent attackers to execute arbitrary commands via crafted input.

Solution

A fix is available, and it can be downloaded from the AIX website.
For AIX 5.3 or AIX 6.1, use perl61.zip, and for AIX 7.1 use perl71.zip.

IMPORTANT : If possible, it is recommended that a mksysb backup of the system be created. Verify it is both bootable and readable before proceeding.

To preview the fix installation :

installp -apYd . perl

To install the fix package :

installp -aXYd . perl
