Ubuntu Security Notice USN-2699-1
July 30, 2015

hplip vulnerability

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

• Ubuntu 15.04
• Ubuntu 14.04 LTS
• Ubuntu 12.04 LTS

Summary:

HPLIP could be tricked into downloading a different GPG key when
performing printer plugin installations.

Software Description:

• hplip: HP Linux Printing and Imaging System (HPLIP)

Details:

Enrico Zini discovered that HPLIP used a short GPG key ID when downloading
keys from the keyserver. An attacker could possibly use this to return a
different key with a duplicate short key id and perform a man-in-the-middle
attack on printer plugin installations.

Update instructions:

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

Ubuntu 15.04:
hplip-data 3.15.2-0ubuntu4.2

Ubuntu 14.04 LTS:
hplip-data 3.14.3-0ubuntu3.4

Ubuntu 12.04 LTS:
hplip-data 3.12.2-1ubuntu3.5

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