02 May 2006 — Buffer overflow in the X render (Xrender) extension in X.org X server 6.8.0 up to allows attackers to cause a denial of service (crash), as demonstrated by the (1) XRenderCompositeTriStrip and (2) XRenderCompositeTriFan requests in the rendertest from XCB xcb/xcb-demo, which leads to an incorrect memory allocation due to a typo in an expression that uses a "&" instead of a "*" operator. NOTE: the subject line of the original announcement used an incorrect CVE number for this issue. • http://lists.freedesktop.org/archives/xorg/2006-May/015136.html •

CVE-2006-0745 – X.Org X11 (X11R6.9.0/X11R7.0) - Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2006-0745
21 Mar 2006 — X.Org server (xorg-server) 1.0.0 and later, X11R6.9.0, and X11R7.0 inadvertently treats the address of the geteuid function as if it is the return value of a call to geteuid, which allows local users to bypass intended restrictions and (1) execute arbitrary code via the -modulepath command line option or (2) overwrite arbitrary files via -logfile. • https://www.exploit-db.com/exploits/1596 •
