Description Mark J. Cox 2003-09-18 13:27:32 UTC 
Multiple integer overflows in the transfer and enumeration of
font libraries for XFree86 4.3.0 allow local or remote
attackers to cause a denial of service or execute arbitrary
code via heap-based and stack-based buffer overflow attacks.

The risk to users is limited because only clients can be
affected by these bugs, however in some (non default)
configurations, both xfs and the X Server can act as clients
to remote font servers.
