USN-1588-1: Software Properties vulnerability

Releases

• Ubuntu 12.04
• Ubuntu 11.10
• Ubuntu 11.04
• Ubuntu 10.04

Packages

• software-properties - manage the repositories that you install software from

Details

It was discovered that the apt-add-repository tool incorrectly validated
PPA GPG keys when importing from a keyserver. If a remote attacker were
able to perform a machine-in-the-middle attack, this flaw could be exploited to
install altered package repository GPG keys.

Update instructions

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

Ubuntu 12.04

• python-software-properties - 0.82.7.3

Ubuntu 11.10

• python-software-properties - 0.81.13.5

Ubuntu 11.04

• python-software-properties - 0.80.9.2

Ubuntu 10.04

• python-software-properties - 0.75.10.3

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