Detailsinfo

A vulnerability, which was classified as critical, was found in lighttpd (Web Server). This affects an unknown code. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as 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. This is going to have an impact on availability. The summary by CVE is:

lighttpd before 1.4.14 allows attackers to cause a denial of service (crash) via a request to a file whose mtime is 0, which results in a NULL pointer dereference.

The bug was discovered 04/16/2007. The weakness was released 04/17/2007 by Robert Jakabosky (Website). The advisory is shared at secunia.com. This vulnerability is uniquely identified as CVE-2007-1870 since 04/05/2007. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 25049 (FreeBSD : lighttpd -- DOS when access files with mtime 0 (5678da43-ea99-11db-a802-000fea2763ce)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family FreeBSD Local Security Checks and running in the context l.

Upgrading to version 1.4.14 eliminates this vulnerability. A possible mitigation has been published before and not just after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (33678), Tenable (25049), SecurityFocus (BID 23515†), OSVDB (34176†) and Secunia (SA24886†). Entries connected to this vulnerability are available at VDB-3015 and VDB-3016. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
