Debian DLA-354-1 : nss security update

High Nessus Plugin ID 87075

Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities have been discovered in nss, the Mozilla Network Security Service library. The Common Vulnerabilities and Exposures project identifies the following problems :

CVE-2015-7181

The sec_asn1d_parse_leaf function improperly restricts access to an unspecified data structure, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted OCTET STRING data, related to a 'use-after-poison' issue.

CVE-2015-7182

A Heap-based buffer overflow in the ASN.1 decoder allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted OCTET STRING data.

For the oldoldstable distribution (squeeze), these problems have been fixed in version 3.12.8-1+squeeze13.

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.
