CentOS Errata and Security Advisory CESA-2016:0684
Network Security Services (NSS) is a set of libraries designed to support the
cross-platform development of security-enabled client and server applications.
Netscape Portable Runtime (NSPR) provides platform independence for non-GUI
operating system facilities.
The following packages have been upgraded to a newer upstream version: nss
3.21.0, nspr 4.11.0. (BZ#1297944, BZ#1297943)
Security Fix(es):
A use-after-free flaw was found in the way NSS handled DHE (Diffie-Hellman key
exchange) and ECDHE (Elliptic Curve Diffie-Hellman key exchange) handshake
messages. A remote attacker could send a specially crafted handshake message
that, when parsed by an application linked against NSS, would cause that
application to crash or, under certain special conditions, execute arbitrary
code using the permissions of the user running the application. (CVE-2016-1978)
A use-after-free flaw was found in the way NSS processed certain DER
(Distinguished Encoding Rules) encoded cryptographic keys. An attacker could use
this flaw to create a specially crafted DER encoded certificate which, when
parsed by an application compiled against the NSS library, could cause that
application to crash, or execute arbitrary code using the permissions of the
user running the application. (CVE-2016-1979)
Red Hat would like to thank the Mozilla project for reporting these issues.
Upstream acknowledges Eric Rescorla as the original reporter of CVE-2016-1978;
and Tim Taubert as the original reporter of CVE-2016-1979.
