Xfree86 Project » X11r6 : Security Vulnerabilities, CVEs, Published In 2000 CVSS score >= 2

libX11 X library allows remote attackers to cause a denial of service via a resource mask of 0, which causes libX11 to go into an infinite loop.

libICE in XFree86 allows remote attackers to cause a denial of service by specifying a large value which is not properly checked by the SKIP_STRING macro.

xterm, Eterm, and rxvt allow an attacker to cause a denial of service by embedding certain escape characters which force the window to be resized.

XFree86 3.3.x and 4.0 allows a user to cause a denial of service via a negative counter value in a malformed TCP packet that is sent to port 6000.

Buffer overflow in XFree86 3.3.x allows local users to execute arbitrary commands via a long -xkbmap parameter.
