Detailsinfo

A vulnerability, which was classified as critical, was found in Linux Kernel 2.6.28.2 (Operating System). This affects the function execve. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on availability. The summary by CVE is:

The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit.

The issue has been introduced in 12/25/2008. The weakness was disclosed 08/18/2009 (Website). It is possible to read the advisory at redhat.com. This vulnerability is uniquely identified as CVE-2009-2848. Attacking locally is a requirement. No form of authentication is needed for exploitation. Technical details of the vulnerability are known, but there is no available exploit.

The vulnerability was handled as a non-public zero-day exploit for at least 236 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 43779 (CentOS 5 : kernel (CESA-2009:1243)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165661 (SUSE Enterprise Linux Security Update Linux Kernel (SUSE-SA:2009:054)).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (52899), Tenable (43779), Secunia (SA36562†) and Vulnerability Center (SBV-23428†).
