Summary
Red Hat Security Advisory: hanterm-xf security update

Notes

Topic
An updated hanterm-xf package to correct a security issue is now available for Red Hat Enterprise Linux 2.1. This update has been rated as having important security impact by the Red Hat Security Response Team.
Details
Hanterm is a replacement for xterm, a X Window System terminal emulator, that supports Hangul input and output. A flaw was found in the Hanterm 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 a Hanterm window. (CVE-2008-2383) All hanterm-xf users are advised to upgrade to the updated package, which contains a backported patch to resolve this issue. All running instances of hanterm must be restarted for the update to take effect.
