Description

Various routines for the ppc64 architecture on Linux kernel 2.6 prior to 2.6.2 and 2.4 prior to 2.4.24 do not use the copy_from_user function when copying data from userspace to kernelspace, which crosses security boundaries and allows local users to cause a denial of service.

Affected products

Linux kernel: 2.4.0-test10, 2.4.0-test11, 2.4.0-test12, 2.4.0-test2, 2.4.0-test3, 2.4.0-test4 (+33)
