Vulnerability Assessment Details
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-2003-026 (kernel).
The kernel package contains the Linux kernel (vmlinuz), the core of your
Red Hat Linux operating system. The kernel handles the basic functions
of the operating system: memory allocation, process allocation, device
input and output, etc.
The kernel shipped with Fedora Core 1 was vulnerable to a bug in the
error return on a concurrent fork() with threaded exit() which could be
exploited by a user level program to crash the kernel.
In addition to this bug fix, the changelog below details various
other non security fixes that have been added.
