Fedora Core 1 2004-251: kernel Vulnerability Scan
Vulnerability Scan Summary
Check for the version of the kernel package
Detailed Explanation for this Vulnerability Test
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.
