Fedora 2004-101 Security Check

High

Synopsis

The remote host is missing a security update.

Description

iDefense reported a buffer overflow flaw in the ISO9660 filesystem code. An attacker could create a malicious filesystem in such a way that they could gain root privileges 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.

Solution

Update the affected package(s).
