A vulnerability classified as critical was found in OpenSSL up to 0.9.8l (Network Encryption Software). Affected by this vulnerability is the function bn_wexpand
. The manipulation with an unknown input leads to a input validation vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:
OpenSSL before 0.9.8m does not check for a NULL return value from bn_wexpand function calls in (1) crypto/bn/bn_div.c, (2) crypto/bn/bn_gf2m.c, (3) crypto/ec/ec2_smpl.c, and (4) engines/e_ubsec.c, which has unspecified impact and context-dependent attack vectors.
The issue has been introduced in 07/05/2005. The weakness was published 03/05/2010 by Neel Mehta (Website). It is possible to read the advisory at marc.info. This vulnerability is known as CVE-2009-3245 since 09/18/2009. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication.
