RHSA-2016:0685 -- nss, nspr, nss-softokn, and nss-util security, bug fix, and enhancement update
Description
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)
