Xsan Filesystem 1.4
Available for: Mac OS X v10.4.7, Mac OS X Server v10.4.7
Impact: Malicious users may be able to cause systems using Xsan to crash or execute arbitrary code
Description: A buffer overflow may occur in the Xsan Filesystem driver when processing a path name. A malicious user with write access to an Xsan volume may be able to trigger the overflow on systems directly attached to Xsan. This could lead to a system crash or arbitrary code execution with system privileges. This update addresses the issue by performing additional validation of path names.
