Description

Updated kernel packages that fix security vulnerabilities which may allow local users to gain root privileges are now available. These packages also resolve other minor issues.

The Linux kernel handles the basic functions of the operating system. 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. The Vicam USB driver in kernel versions prior to 2.4.25 does not use the copy_from_user function to access userspace, which crosses security boundaries. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0075 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. Alan Cox found issues in the R128 Direct Render Infrastructure that could allow local privilege escalation. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0003 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.
