USN-2878-1: Perl vulnerability

21 January 2016

Perl incorrectly handled the taint attribute.



  • perl - Practical Extraction and Report Language


David Golden discovered that the canonpath function in the Perl File::Spec
module did not properly preserve the taint attribute. An attacker could
possibly use this issue to bypass the taint protection mechanism.

Update instructions

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

Ubuntu 15.10
Ubuntu 15.04

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