Detailsinfo

A vulnerability was found in Linux Kernel (Operating System). It has been rated as problematic. This issue affects the function huft_build of the file inflate.c. The manipulation with an unknown input leads to a null pointer dereference vulnerability. Using CWE to declare the problem leads to CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. Impacted is availability. The summary by CVE is:

The huft_build function in inflate.c in the zlib routines in the Linux kernel before 2.6.12.5 returns the wrong value, which allows remote attackers to cause a denial of service (kernel crash) via a certain compressed file that leads to a null pointer dereference, a different vulnerbility than CVE-2005-2458.

The bug was discovered 08/19/2005. The weakness was shared 08/23/2005 with Gentoo (Website). It is possible to read the advisory at secunia.com.
