3. Description:
The xterm program is a terminal emulator for the X Window System.
A flaw was found in the xterm handling of Device Control Request Status
String (DECRQSS) escape sequences. An attacker could create a malicious
text file (or log entry, if unfiltered) that could run arbitrary commands
if read by a victim inside an xterm window. (CVE-2008-2383)
All xterm users are advised to upgrade to the updated package, which
contains a backported patch to resolve this issue. All running instances of
xterm must be restarted for the update to take effect.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
