Debian Security Advisory DSA-3998-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso
October 11, 2017 https://www.debian.org/security/faq
Package : nss
CVE ID : CVE-2017-7805
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.
