Summary
Red Hat Security Advisory: : New xloadimage packages available

Notes

Topic
These updated packages fix a buffer overflow in the faces reader. This is normally not a security problem; however, xloadimage is called by the 'plugger' program from inside Netscape to handle some image types. Hence, a remote site could cause arbitrary code to be executed as the user running Netscape. It is recommended that users of Netscape and plugger update to the fixed xloadimage packages. Plugger was shipped in Red Hat Powertools 6.2; if you have only installed packages from Red Hat Linux 6.2, you are not vulnerable to this exploit.
Details
A buffer overflow existed in the faces reader for xloadimage. By making a specially constructed invalid faces file, and then having the server serve this file as a .tif file, arbitrary code could be executed on the client computer running Netscape. Thanks go to empathy@feelings.com for bringing this problem to our attention.

Many\npeople find this an easier way to apply updates.  To use Red Hat Network,\nlaunch the Red Hat Update Agent with the following command:\n\nup2date\n\nThis will start an interactive process that will result in the appropriate\nRPMs being upgraded on your system.",
