Published: 2015-11-05 05:16:03
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:P/I:P/A:P

Detection Type:
Linux Distribution Package

Summary:
Check the version of nspr

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
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 Linux Distribution Packages to completely resolve the CVE-2015-7183 issue. This erratum includes nss and nss-utils Linux Distribution 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 Linux Distribution Packages, which contain backported patches to correct these issues.

Affected Versions:
nspr on CentOS 6

Recommendations:
Please install the updated Linux Distribution Packages.

Solution Type:
Vendor Patch

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
