Debian DLA-1157-1 : openssl security update

Medium Nessus Plugin ID 104481

Synopsis

The remote Debian host is missing a security update.

Description

A security vulnerability was discovered in OpenSSL, the Secure Sockets Layer toolkit.

CVE-2017-3735

It was discovered that OpenSSL is prone to a one-byte buffer overread while parsing a malformed IPAddressFamily extension in an X.509 certificate.

Details can be found in the upstream advisory:
https://www.openssl.org/news/secadv/20170828.txt

For Debian 7 'Wheezy', these problems have been fixed in version 1.0.1t-1+deb7u3.

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.
