Fedora Security Update Notification
FEDORA-2004-079
2004-02-18
---------------------------------------------------------------------

Name        : kernel
Version     : 2.4.22                      
Release     : 1.2173.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
Fedora Core 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 return value checking in mremap() in the
Linux kernel versions 2.4.24 and previous that may allow a local attacker
to gain root privileges.  No exploit is currently available; however this
issue is exploitable. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0077 to this issue.

Arjan van de Ven discovered a flaw in ncp_lookup() in ncpfs that could
allow local privilege escalation.  ncpfs is only used to allow a system to
mount volumes of NetWare servers or print to NetWare printers.  The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CAN-2004-0010 to this issue.

All users are advised to upgrade to these errata packages, which contain
backported security patches that correct these issues.   

Red Hat would like to thank Paul Starzetz from ISEC for reporting the issue
CAN-2004-0077.
