The remote host is affected by the vulnerability described in GLSA-200710-16 (X.Org X server: Composite local privilege escalation)
Aaron Plattner discovered a buffer overflow in the compNewPixmap() function when copying data from a large pixel depth pixmap into a smaller pixel depth pixmap.
Impact :
A local attacker could execute arbitrary code with the privileges of the user running the X server, typically root.
Workaround :
Disable the Composite extension by setting ' Option 'Composite' 'disable' ' in the Extensions section of xorg.conf.
Note: This could affect the functionality of some applications.
