Ubuntu 4.10 / 5.04 : python2.1, python2.2, python2.3, gnumeric vulnerabilities (USN-173-4)

high Nessus Plugin ID 20583

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
