===========================================================
Ubuntu Security Notice USN-264-1       March 13, 2006
gnupg vulnerability
CVE-2006-0049
===========================================================

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:

gnupg

The problem can be corrected by upgrading the affected package to
version 1.2.4-4ubuntu2.3 (for Ubuntu 4.10), 1.2.5-3ubuntu5.3 (for
Ubuntu 5.04), or 1.4.1-1ubuntu1.2 (for Ubuntu 5.10).  In general, a
standard system upgrade is sufficient to effect the necessary changes.

Details follow:

Tavis Ormandy discovered a flaw in gnupg's signature verification. In
some cases, certain invalid signature formats could cause gpg to
report a 'good signature' result for auxiliary unsigned data which was
prepended or appended to the checked message part.
