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 escape sequences. An attacker could create a malicious text file that could run arbitrary commands if read by a victim inside a Hanterm window. 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.
