RHEL 5 : openssl (RHSA-2016:1137)

critical Nessus Plugin ID 91380

Synopsis

The remote Red Hat host is missing a security update for openssl.

Description

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2016:1137 advisory.

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library.

Security Fix(es):

* A flaw was found in the way OpenSSL encoded certain ASN.1 data structures. An attacker could use this flaw to create a specially crafted certificate which, when verified or re-encoded by OpenSSL, could cause it to crash, or execute arbitrary code using the permissions of the user running an application compiled against the OpenSSL library. (CVE-2016-2108)

Red Hat would like to thank the OpenSSL project for reporting this issue. Upstream acknowledges Huzaifa Sidhpurwala (Red Hat), Hanno Bck, and David Benjamin (Google) as the original reporters.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL openssl package based on the guidance in RHSA-2016:1137.
