New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems :

- CVE-2008-3528 Eugene Teo reported a local DoS issue in the ext2 and ext3 filesystems. Local users who have been granted the privileges necessary to mount a filesystem would be able to craft a corrupted filesystem that causes the kernel to output error messages in an infinite loop.

- CVE-2008-4554 Milos Szeredi reported that the usage of splice() on files opened with O_APPEND allows users to write to the file at arbitrary offsets, enabling a bypass of possible assumed semantics of the O_APPEND flag.

- CVE-2008-4576 Vlad Yasevich reported an issue in the SCTP subsystem that may allow remote users to cause a local DoS by triggering a kernel oops.

- CVE-2008-4618 Wei Yongjun reported an issue in the SCTP subsystem that may allow remote users to cause a local DoS by triggering a kernel panic.

- CVE-2008-4933 Eric Sesterhenn reported a local DoS issue in the hfsplus filesystem. Local users who have been granted the privileges necessary to mount a filesystem would be able to craft a corrupted filesystem that causes the kernel to overrun a buffer, resulting in a system oops or memory corruption.

- CVE-2008-4934 Eric Sesterhenn reported a local DoS issue in the hfsplus filesystem. Local users who have been granted the privileges necessary to mount a filesystem would be able to craft a corrupted filesystem that results in a kernel oops due to an unchecked return value.

- CVE-2008-5025 Eric Sesterhenn reported a local DoS issue in the hfs filesystem. Local users who have been granted the privileges necessary to mount a filesystem would be able to craft a filesystem with a corrupted catalog name length, resulting in a system oops or memory corruption.

- CVE-2008-5029 Andrea Bittau reported a DoS issue in the unix socket subsystem that allows a local user to cause memory corruption, resulting in a kernel panic.

- CVE-2008-5134 Johannes Berg reported a remote DoS issue in the libertas wireless driver, which can be triggered by a specially crafted beacon/probe response.

- CVE-2008-5182 Al Viro reported race conditions in the inotify subsystem that may allow local users to acquire elevated privileges.

- CVE-2008-5300 Dann Frazier reported a DoS condition that allows local users to cause the out of memory handler to kill off privileged processes or trigger soft lockups due to a starvation issue in the unix socket subsystem.

Solution

Upgrade the linux-2.6.24 packages.

For the stable distribution (etch), these problems have been fixed in version 2.6.24-6~etchnhalf.7.
