Paul Staretz discovered a flaw in return value checking in the
mremap() function in the Linux kernel, versions 2.4.24 and previous
that could allow a local user to obtain root privileges.
A vulnerability was found in the R128 DRI driver by Alan Cox. This
could allow local privilege escalation.
A flaw in the ncp_lookup() function in the ncpfs code (which is used
to mount NetWare volumes or print to NetWare printers) was found by
Arjen van de Ven that could allow local privilege escalation.
The Vicam USB driver in Linux kernel versions prior to 2.4.25 does
not use the copy_from_user function to access userspace, which crosses
security boundaries. This problem does not affect the Mandrake Linux
Additionally, a ptrace hole that only affects the amd64/x86_64
platform has been corrected.
