Debian DLA-946-1 : nss security update

High Nessus Plugin ID 100302

Synopsis

The remote Debian host is missing a security update.

Description

The NSS library is vulnerable to two security issues :

CVE-2017-5461

Out-of-bounds write in Base64 encoding. This can trigger a crash (denial of service) and might be exploitable for code execution.

CVE-2017-5462

A flaw in DRBG number generation where the internal state V does not correctly carry bits over.

For Debian 7 'Wheezy', these problems have been fixed in version 2:3.26-1+debu7u3.

We recommend that you upgrade your nss 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.
