OpenSSL 1.0.1 < 1.0.1o Vulnerability

critical Nessus Plugin ID 90888

Language:

Synopsis

The remote service is affected by a vulnerability.

Description

The version of OpenSSL installed on the remote host is prior to 1.0.1o. It is, therefore, affected by a vulnerability as referenced in the 1.0.1o advisory.

- The ASN.1 implementation in OpenSSL before 1.0.1o and 1.0.2 before 1.0.2c allows remote attackers to execute arbitrary code or cause a denial of service (buffer underflow and memory corruption) via an ANY field in crafted serialized data, aka the negative zero issue. (CVE-2016-2108)

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 1.0.1o or later.
