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

- Ubuntu 12.10
- Ubuntu 12.04 LTS

Summary:

Perl could be made to stop responding if it received specially crafted
input.

Details:

Yves Orton discovered that Perl incorrectly handled hashing when using
user-provided hash keys. An attacker could use this flaw to perform a
denial of service attack against software written in Perl.

Ubuntu 12.04 LTS:
  perl                            5.14.2-6ubuntu2.3

Ubuntu 11.10:
  perl                            5.12.4-4ubuntu0.2

Ubuntu 10.04 LTS:
  perl                            5.10.1-8ubuntu2.3

Ubuntu 8.04 LTS:
