Integer overflow in the CIDAFM function in X.Org 6.8.2 and XFree86 X server allows local users to execute arbitrary code via crafted Adobe Font Metrics (AFM) files with a modified number of character metrics (StartCharMetrics), which leads to a heap-based buffer overflow.

Integer overflow in the scan_cidfont function in X.Org 6.8.2 and XFree86 X server allows local users to execute arbitrary code via crafted (1) CMap and (2) CIDFont font data with modified item counts in the (a) begincodespacerange, (b) cidrange, and (c) notdefrange sections.

Multiple integer overflows in XFree86 before 4.3.0 allow user-assisted attackers to execute arbitrary code via a crafted pixmap image.

dexconf in XFree86 Xserver 4.1.0-2 creates the /dev/dri directory with insecure permissions (666), which allows local users to replace or create files in the root file system.

SGI IRIX buffer overflow in xterm and Xaw allows root access.
