DESCRIPTION:
Dan Rosenberg has reported a vulnerability in Apple Mac OS X, which
can be exploited by malicious, local users to cause a DoS (Denial of
Service).
The vulnerability is caused due to the "webdav_mount()" function of
the WebDAV kernel extension not properly verifying certain parameters
before using them to allocate memory, which can be exploited to
trigger a kernel panic.
SOLUTION:
Restrict access to trusted users only.
