OpenSSL 1.0.0 < 1.0.0d Vulnerability

critical Nessus Plugin ID 51919

Language:

Synopsis

The remote service is affected by a vulnerability.

Description

The version of OpenSSL installed on the remote host is prior to 1.0.0d. It is, therefore, affected by a vulnerability as referenced in the 1.0.0d advisory.

- ssl/t1_lib.c in OpenSSL 0.9.8h through 0.9.8q and 1.0.0 through 1.0.0c allows remote attackers to cause a denial of service (crash), and possibly obtain sensitive information in applications that use OpenSSL, via a malformed ClientHello handshake message that triggers an out-of-bounds memory access, aka OCSP stapling vulnerability. (CVE-2011-0014)

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 1.0.0d or later.
