Scientific Linux Security Update : spice-xpi on SL5.x i386/x86_64

low Nessus Plugin ID 60845

Language:

Synopsis

The remote Scientific Linux host is missing a security update.

Description

The spice-xpi package provides a plug-in that allows the SPICE client to run from within Mozilla Firefox.

A race condition was found in the way the SPICE Firefox plug-in and the SPICE client communicated. A local attacker could use this flaw to trick the plug-in and the SPICE client into communicating over an attacker-controlled socket, possibly gaining access to authentication details, or resulting in a man-in-the-middle attack on the SPICE connection. (CVE-2010-2792)

It was found that the SPICE Firefox plug-in used a predictable name for its log file. A local attacker could use this flaw to conduct a symbolic link attack, allowing them to overwrite arbitrary files accessible to the user running Firefox. (CVE-2010-2794)

This update also fixes the following bugs :

- a bug prevented users of Red Hat Enterprise Linux 5.5, with all updates applied, from running the SPICE Firefox plug-in when using Firefox 3.6.4. With this update, the plug-in works correctly with Firefox 3.6.4 and the latest version in Red Hat Enterprise Linux 5.5, Firefox 3.6.7. (BZ#618244)

- unused code has been removed during source code refactoring. This also resolves a bug in the SPICE Firefox plug-in that caused it to close random file descriptors. (BZ#594006, BZ#619067)

Note: This update should be installed together with the qspice-client security update.

After installing the update, Firefox must be restarted for the changes to take effect.

Solution

Update the affected spice-xpi package.
