DLA-1138-1 nss -- LTS security update

Date Reported:
19 Oct 2017
Affected Packages:
Security database references:
In Mitre's CVE dictionary: CVE-2017-7805.
More information:

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 Debian 7 Wheezy, these problems have been fixed in version 2:3.26-1+debu7u5.

We recommend that you upgrade your nss packages.
