Discussion
X.Org X Server PCF Font Parser Buffer Overflow Vulnerability
X.Org X Server is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input.
Attackers can exploit this issue to execute arbitrary code with the privileges of the server. Failed attacks will cause denial-of-service conditions.
NOTE: This vulnerability was previously covered in BID 27336 (X.Org X Server Multiple Local Privilege Escalation and Information Disclosure Vulnerabilities), but has been given its own record to better document the issue.
