Fedora Core 1 2004-101: kernel

Vulnerability Assessment Summary 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-2004-101 (kernel). 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. Update Information: iDefense reported a buffer overflow flaw in the ISO9660 filesystem code. A possible hacker could create a malicious filesystem in such a way that they could gain root rights if that filesystem is mounted. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0109 to this issue. Solar Designer from OpenWall discovered a minor information leak in the ext3 filesystem code due to the lack of initialization of journal descriptor blocks. This flaw has only minor security implications and exploitation requires privileged access to the raw device. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0133 to this issue. These packages also contain an updated fix with additional checks for issues in the R128 Direct Render Infrastructure. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0003 to this issue. Additionally, additional hardening of the mremap function was applied to prevent a potential local denial of service attack. The low latency patch applied in previous kernels has also been found to cause stability problems under certain conditions. It has been disabled in this update whilst further investigation occurs.
