Scientific Linux Security Update : nss, nss-util, and nspr on SL6.x, SL7.x i386/x86_64

High Nessus Plugin ID 86750

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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.

Solution

Update the affected packages.
