Releases

• Ubuntu 13.04
• Ubuntu 12.10
• Ubuntu 12.04

Packages

• 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

• libmodule-signature-perl - 0.68-1ubuntu0.12.10.1

Ubuntu 12.04

• libmodule-signature-perl - 0.68-1ubuntu0.12.04.1
