Red Hat Product Security has rated this update as having a security
impact of Critical. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.
The nss-util packages provide utilities for use with the Network
Security Services (NSS) libraries.
Security Fix(es) :
* An out-of-bounds write flaw was found in the way NSS performed
certain Base64-decoding operations. An attacker could use this flaw to
create a specially crafted certificate which, when parsed by NSS,
could cause it to crash or execute arbitrary code, using the
permissions of the user running an application compiled against the
NSS library. (CVE-2017-5461)
Red Hat would like to thank the Mozilla project for reporting this
issue. Upstream acknowledges Ronald Crane as the original reporter.
