RHEL 6 : nss, nss-util, and nspr (RHSA-2015:2068)

critical Nessus Plugin ID 86910

Synopsis

The remote Red Hat host is missing one or more security updates for nss / nss-util / nspr.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:2068 advisory.

Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. Netscape Portable Runtime (NSPR) provides platform independence for non-GUI operating system facilities.

A use-after-poison flaw and a heap-based buffer overflow flaw were found in the way NSS parsed certain ASN.1 structures. An attacker could use these flaws to cause NSS to crash or execute arbitrary code with the permissions of the user running an application compiled against the NSS library.
(CVE-2015-7181, CVE-2015-7182)

A heap-based buffer overflow was found in NSPR. An attacker could use this flaw to cause NSPR to crash or execute arbitrary code with the permissions of the user running an application compiled against the NSPR library.
(CVE-2015-7183)

Note: Applications using NSPR's PL_ARENA_ALLOCATE, PR_ARENA_ALLOCATE, PL_ARENA_GROW, or PR_ARENA_GROW macros need to be rebuilt against the fixed nspr packages to completely resolve the CVE-2015-7183 issue. This erratum includes nss and nss-utils packages rebuilt against the fixed nspr version.

Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Tyson Smith, David Keeler, and Ryan Sleevi as the original reporters.

All nss, nss-util, and nspr users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

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

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

Solution

Update the RHEL nss / nss-util / nspr packages based on the guidance in RHSA-2015:2068.
