Summary
Red Hat Security Advisory: hanterm-xf security update
Severity
Important
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.

CVE-2008-2383
