Test ID:1.3.6.1.4.1.25623.1.0.882318
Category:CentOS Local Security Checks
Title:CentOS Update for nspr CESA-2015:1981 centos7
Summary:Check the version of nspr
Description:Summary:
Check the version of nspr

Vulnerability Insight:
Network Security Services (NSS) is a set of libraries designed to support
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 rebuild 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 reporter.

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

Affected Software/OS:
nspr on CentOS 7

Solution:
Please install the updated packages.
