Test ID:1.3.6.1.4.1.25623.1.0.56027
Category:Ubuntu Local Security Checks
Title:Ubuntu USN-222-2 (perl)
Summary:Ubuntu USN-222-2 (perl)
Description:
The remote host is missing an update to perl
announced via advisory USN-222-2.

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)
Ubuntu 5.10 (Breezy Badger)

The following packages are affected: libperl5.8 perl-base

USN-222-1 fixed a vulnerability in the Perl interpreter. It was
discovered that the version of USN-222-1 was not sufficient to handle
all possible cases of malformed input that could lead to arbitrary
code execution, so another update is necessary.

Original advisory:

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 privileges 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:
The problem can be corrected by upgrading the affected package to
version 5.8.4-2ubuntu0.6 (for Ubuntu 4.10), 5.8.4-6ubuntu1.2 (for
Ubuntu 5.04), or 5.8.7-5ubuntu1.2 (for Ubuntu 5.10). In general, a
standard system upgrade is sufficient to effect the necessary changes.
