| Description: | Description:
The remote host is missing an update to ruby1.8
announced via advisory USN-596-1.
A security issue affects the following Ubuntu releases:
Ubuntu 6.06 LTS
Ubuntu 6.10
Ubuntu 7.04
Ubuntu 7.10
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
Details follow:
Chris Clark discovered that Ruby's HTTPS module did not check for
commonName mismatches early enough during SSL negotiation. If a remote
attacker were able to perform man-in-the-middle attacks, this flaw could
be exploited to view sensitive information in HTTPS requests coming from
Ruby applications. (CVE-2007-5162)
It was discovered that Ruby's FTPTLS, telnets, and IMAPS modules
did not check the commonName when performing SSL certificate checks.
If a remote attacker were able to perform man-in-the-middle attacks,
this flaw could be exploited to eavesdrop on encrypted communications
from Ruby applications using these protocols. (CVE-2007-5770)
Solution:
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 6.06 LTS:
libopenssl-ruby1.8 1.8.4-1ubuntu1.4
libruby1.8 1.8.4-1ubuntu1.4
Ubuntu 6.10:
libopenssl-ruby1.8 1.8.4-5ubuntu1.3
libruby1.8 1.8.4-5ubuntu1.3
Ubuntu 7.04:
libopenssl-ruby1.8 1.8.5-4ubuntu2.1
libruby1.8 1.8.5-4ubuntu2.1
Ubuntu 7.10:
libopenssl-ruby1.8 1.8.6.36-1ubuntu3.1
libruby1.8 1.8.6.36-1ubuntu3.1
In general, a standard system upgrade is sufficient to effect the
necessary changes.
