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 roject
(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.
