Debian DLA-814-1 : openssl security update

high Nessus Plugin ID 96931

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities were discovered in OpenSSL :

CVE-2016-7056

A local timing attack was discovered against ECDSA P-256.

CVE-2016-8610

It was discovered that no limit was imposed on alert packets during an SSL handshake.

CVE-2017-3731

Robert Swiecki discovered that the RC4-MD5 cipher when running on 32 bit systems could be forced into an out-of-bounds read, resulting in denial of service.

For Debian 7 'Wheezy', these problems have been fixed in version 1.0.1t-1+deb7u2.

We recommend that you upgrade your openssl packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
