Detailsinfo

A vulnerability was found in Gnome evolution-data-server 2.24.5/2.25.92. It has been rated as problematic. This issue affects the function ntlm_challenge. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, and availability. The summary by CVE is:

The ntlm_challenge function in the NTLM SASL authentication mechanism in camel/camel-sasl-ntlm.c in Camel in Evolution Data Server (aka evolution-data-server) 2.24.5 and earlier, and 2.25.92 and earlier 2.25.x versions, does not validate whether a certain length value is consistent with the amount of data in a challenge packet, which allows remote mail servers to read information from the process memory of a client, or cause a denial of service (client crash), via an NTLM authentication type 2 packet with a length value that exceeds the amount of packet data.

The bug was discovered 03/12/2009. The weakness was released 03/14/2009 by Matt (Website). The advisory is shared at redhat.com. The identification of this vulnerability is CVE-2009-0582 since 02/13/2009. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are known, but no exploit is available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 2 days. During that time the estimated underground price was around $0-$5k.
