X Window System behaves unpredictably when handling an overly large font size. If an attacker can pass an overly large font size to X Window System, it is possible to cause a denial of service condition.
|
|
|
|
Remote exploitation of this issue is possible via web clients or other applications which do not check that the font size is sane before passing it to the X Window System. This is reported to be a problem with xfs (X Font Server) and the libXfont component.
|
|
|
|
This is reported to affect various X Window System implementations, including XFree86.
