Martin Thomson discovered that nss, the Mozilla Network Security Service library, is prone to a use-after-free vulnerability in the TLS 1.2 implementation when handshake hashes are generated. A remote attacker can take advantage of this flaw to cause an application using the nss library to crash, resulting in a denial of service, or potentially to execute arbitrary code. For the oldstable distribution (jessie), this problem has been fixed in version 2:3.26-1+debu8u3. For the stable distribution (stretch), this problem has been fixed in version 2:3.26.2-1.1+deb9u1. For the testing distribution (buster), this problem has been fixed in version 2:3.33-1. For the unstable distribution (sid), this problem has been fixed in version 2:3.33-1. We recommend that you upgrade your nss packages.
