OpenSSL 0.9.8v < 0.9.8w Vulnerability

critical Nessus Plugin ID 200192

Language:

Synopsis

The remote service is affected by a vulnerability.

Description

The version of OpenSSL installed on the remote host is prior to 0.9.8w. It is, therefore, affected by a vulnerability as referenced in the 0.9.8w advisory.

- Multiple integer signedness errors in crypto/buffer/buffer.c in OpenSSL 0.9.8v allow remote attackers to conduct buffer overflow attacks, and cause a denial of service (memory corruption) or possibly have unspecified other impact, via crafted DER data, as demonstrated by an X.509 certificate or an RSA public key. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-2110. (CVE-2012-2131)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to OpenSSL version 0.9.8w or later.
