| Description: | Description:
The remote host is missing an update to gnumeric
announced via advisory USN-173-4.
A security issue affects the following Ubuntu releases:
Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)
The following packages are affected:
gnumeric python2.1 python2.2 python2.3
USN-173-1 fixed a buffer overflow vulnerability in the PCRE library.
However, it was found that the various python packages and gnumeric
contain static copies of the library code, so these packages need to
be updated as well.
In gnumeric this bug could be exploited to execute arbitrary code with
the privileges of the user if the user was tricked into opening a
specially crafted spreadsheet document.
In python, the impact depends on the particular application that uses
python's re (regular expression) module. In python server
applications that process unchecked arbitrary regular expressions with
the re module, this could potentially be exploited to remotely
execute arbitrary code with the privileges of the server.
Solution:
On Ubuntu 4.10, the problem can be corrected by upgrading the affected
package to version 1.2.13-1ubuntu2.1 (gnumeric), 2.1.3-24.ubuntu0.1
(python2.1), 2.2.3-10.ubuntu0.2 (python2.2), and 2.3.4-2.ubuntu0.2
(python2.3).
On Ubuntu 5.04, the problem can be corrected by upgrading the affected
package to version 1.4.2-1ubuntu3.1 (gnumeric), 2.2.3dfsg-1ubuntu0.1
(python2.2), and 2.3.5-2ubuntu0.1 (python2.3).
After performing a standard system upgrade you need to restart
gnumeric and all python server applications to effect the necessary
changes.
