DSA-1864-1 linux-2.6.24 -- privilege escalation

Debian Security Advisory

DSA-1864-1 linux-2.6.24 -- privilege escalation

Date Reported:

16 Aug 2009

Affected Packages:

linux-2.6.24

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2009-2692.

More information:

A vulnerability has been discovered in the Linux kernel that may lead to privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problem:

• CVE-2009-2692

  Tavis Ormandy and Julien Tinnes discovered an issue with how the sendpage function is initialized in the proto_ops structure. Local users can exploit this vulnerability to gain elevated privileges.

For the oldstable distribution (etch), this problem has been fixed in version 2.6.24-6~etchnhalf.8etch4.

We recommend that you upgrade your linux-2.6.24 packages.

Note: Debian 'etch' includes linux kernel packages based upon both the 2.6.18 and 2.6.24 linux releases. All known security issues are carefully tracked against both packages and both packages will receive security updates until security support for Debian 'etch' concludes. However, given the high frequency at which low-severity security issues are discovered in the kernel and the resource requirements of doing an update, lower severity 2.6.18 and 2.6.24 updates will typically release in a staggered or "leap-frog" fashion.

Fixed in:

Debian GNU/Linux 4.0 (etch)
