USN-914-1: Linux kernel vulnerabilities

Publication date

17 March 2010

Overview

Linux kernel vulnerabilities


Details

Mathias Krause discovered that the Linux kernel did not correctly handle
missing ELF interpreters. A local attacker could exploit this to cause the
system to crash, leading to a denial of service. (CVE-2010-0307)

Marcelo Tosatti discovered that the Linux kernel's hardware virtualization
did not correctly handle reading the /dev/port special device. A local
attacker in a guest operating system could issue a specific read that
would cause the host system to crash, leading to a denial of service.
(CVE-2010-0309)

Sebastian Krahmer discovered that the Linux kernel did not correctly
handle netlink connector messages. A local attacker could exploit this
to consume kernel memory, leading to a denial of service. (CVE-2010-0410)

Ramon de Carvalho Valle discovered that the Linux kernel did not correctly
validate...

to consume kernel memory, leading to a denial of service. (CVE-2010-0410)

Ramon de Carvalho Valle discovered that the Linux kernel did not correctly
validate certain memory migration calls. A local attacker could exploit
this to read arbitrary kernel memory or cause a system crash, leading
to a denial of service. (CVE-2010-0415)

Jermome Marchand and Mikael Pettersson discovered that the Linux kernel
did not correctly handle certain futex operations. A local attacker could
exploit this to cause a system crash, leading to a denial of service.
(CVE-2010-0622, CVE-2010-0623)


Update instructions

After a standard system upgrade you need to reboot your computer to effect the necessary changes.

Learn more about how to get the fixes.

The problem can be corrected by updating your system to the following package versions:
