Subject: [USN-432-2] GnuPG2, GPGME vulnerability
===========================================================
Ubuntu Security Notice USN-432-2 March 13, 2007
gnupg2, gpgme1.0 vulnerability
CVE-2007-1263
===========================================================
A security issue affects the following Ubuntu releases:
Ubuntu 6.06 LTS
Ubuntu 6.10
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 6.06 LTS:
libgpgme11 1.1.0-1ubuntu0.1
Ubuntu 6.10:
gnupg2 1.9.21-0ubuntu5.3
libgpgme11 1.1.2-2ubuntu0.1
In general, a standard system upgrade is sufficient to effect the
necessary changes.
Details follow:
USN-432-1 fixed a vulnerability in GnuPG. This update provides the
corresponding updates for GnuPG2 and the GPGME library.
Original advisory details:
Gerardo Richarte from Core Security Technologies discovered that when
gnupg is used without --status-fd, there is no way to distinguish
initial unsigned messages from a following signed message. An attacker
could inject an unsigned message, which could fool the user into
thinking the message was entirely signed by the original sender.
Updated packages for Ubuntu 6.06 LTS:
