Description Mark J. Cox (Product Security) 2004-06-21 05:53:15 EDT
"The Vicam USB driver does not use the copy_from_user function when
copying data from userspace to kernel space, which crosses security
boundaries and allows local users to cause a denial of service."

(Note for RHEL3 this driver is in unsupported)

Comment 1 Ernie Petrides 2004-06-21 19:55:51 EDT
Pete, since this driver is unsupported in RHEL3, fixing this problem
is not justified in a security errata or in U3.  But I'd like to get
a fix in during U4, since the patches are available and simple.
Comment 2 Pete Zaitcev 2005-02-03 15:48:30 EST
The second patch is not applicable, we have that hole plugged already.
