3. Description:

 

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.
