Synopsis
The remote host is missing a vendor-supplied security patch
Description
The remote host is missing the patch for the advisory SUSE-SA:2004:024 (kernel).
This kernel is vulnerable to a race condition in the 64-bit file offset handling code.
The file offset pointer (f_pos) is changed during reading, writing, and seeking through a file to point to the current position in a file.
The Linux kernel offers a 32bit and a 64bit API. Unfortunately the value conversion between this two APIs as well as the access to the f_pos pointer is defective.
An attacker, exploiting this flaw, would need local access to the machine. Upon successful exploitation, an attacker would be able to read potentially confidential kernel memory.
Additionally a bug in the implementation of chown(2) for updating inode times, and a denial-of-service condition that can occur while handling signals was fixed.
