[SECURITY] Fedora Core 1 Update: kernel-2.4.22-1.2138.nptl

---------------------------------------------------------------------
Fedora Security Update Notification
FEDORA-2003-046

---------------------------------------------------------------------

Name        : kernel
Version     : 2.4.22                      
Release     : 1.2138.nptl                  
Summary     : The Linux kernel (the core of the Linux operating system)
Description :
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.

Paul Starzetz discovered a flaw in bounds checking in mremap() in the Linux
kernel versions 2.4.23 and previous which may allow a local attacker to
gain root privileges.  No exploit is currently available; however, it is
believed that this issue is exploitable (although not trivially.) The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2003-0985 to this issue.

All users are advised to upgrade to these errata packages, which contain a
backported security patch that corrects this issue.  

Red Hat would like to thank Paul Starzetz from ISEC for disclosing this
issue as well as Andrea Arcangeli and Solar Designer for working on the patch.

These packages also contain a fix for a minor information leak in the real
time clock (rtc) routines. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2003-0984 to this issue.
