Title: Multiple Vendor xterm (and derivatives) Denial of Service Vulnerability
Severity: MODERATE
Description:
xterm is a popular X11-based terminal emulator. If VT control-characters are displayed in the xterm, they can be interpreted and used to cause a denial of service attack against the client (and even the host running the client). What makes it possible for remote users to exploit this vulnerability is a situation like this:
An admin is tailing the http access log
Attacker requests url with control characters in it
Admin's xterm crashes
This vulnerability also affects applications (such as other terminal emulators) derived from xterm code.
Affected Products:
- Michael Jennings Eterm 0.8.10
- Simon Tatham PuTTY 0.48.0
- XFree86 X11R6 3.3.3
- XFree86 X11R6 4.0.0
- rxvt rxvt 2.6.1
