The following packages have been upgraded to a newer upstream version:
nss 3.21.0, nspr 4.11.0.
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)
