Summary

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.
