Vulnerability Assessment Details

USN222-1 : perl vulnerability

Vulnerability Assessment Summary
perl vulnerability

Detailed Explanation for this Vulnerability Assessment

Summary :

These remote packages are missing security patches :
- libcgi-fast-perl
- libperl-dev
- libperl5.8
- perl
- perl-base
- perl-debug
- perl-doc
- perl-modules
- perl-suid


Description :

Jack Louis of Dyad Security discovered that Perl did not sufficiently
check the explicit length argument in format strings. Specially
crafted format strings with overly large length arguments led to a
crash of the Perl interpreter or even to execution of arbitrary
attacker-defined code with the rights of the user running the Perl
program.

However, this attack was only possible in insecure Perl programs which
use variables with user-defined values in string interpolations
without checking their validity.

Solution :

Upgrade to :
- libcgi-fast-perl-5.8.7-5ubuntu1.1 (Ubuntu 5.10)
- libperl-dev-5.8.7-5ubuntu1.1 (Ubuntu 5.10)
- libperl5.8-5.8.7-5ubuntu1.1 (Ubuntu 5.10)
- perl-5.8.7-5ubuntu1.1 (Ubuntu 5.10)
- perl-base-5.8.7-5ubuntu1.1 (Ubuntu 5.10)
- perl-debug-5.8.7-5ubuntu1.1 (Ubuntu 5.10)
- perl-doc-5.8.7-5ubuntu1.1 (Ubuntu 5.10)
- perl-modules-5.8.7-5ubuntu1.1 (Ubuntu 5.10)
- perl-suid-5.8.7-5ubuntu1.1 (Ubuntu 5.10)
