Mandrakelinux Security Update Advisory
Package name: kernel
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 9.2 kernel.
Additionally, a ptrace hole that only affects the amd64/x86_64 platform has been corrected.
The provided packages are patched to fix these vulnerabilities. All users are encouraged to upgrade to these updated kernels.
To update your kernel, please follow the directions located at:
