Ubuntu Security Notice USN-1896-1
July 03, 2013

libmodule-signature-perl vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS

Summary:

Module::Signature could be made to run programs if it verified a signature.

Software Description:
- libmodule-signature-perl: module to manipulate CPAN SIGNATURE files

Details:

Florian Weimer discovered that the Module::Signature perl module
incorrectly loaded unknown ciphers from relative directories. An attacker
could possibly use this flaw to execute arbitrary code when a signature is
verified.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 13.04:
libmodule-signature-perl 0.68-1ubuntu0.13.04.1

Ubuntu 12.10:
libmodule-signature-perl 0.68-1ubuntu0.12.10.1

Ubuntu 12.04 LTS:
libmodule-signature-perl 0.68-1ubuntu0.12.04.1

In general, a standard system update will make all the necessary changes.
