Vulnerability Assessment Details

Fedora Core 1 2004-251: kernel

Vulnerability Assessment Summary
Check for the version of the kernel package

Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory FEDORA-2004-251 (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.

A possible hacker, exploiting this flaw, would need local access to the
machine. Upon successful exploitation, a possible hacker would be able
to read potentially confidential kernel memory.

Additionally, a number of issues were fixed in the USB serial code.
