Description

nss 3.12.8-1+squeeze11 fixes two security issues :

CVE-2011-3389

SSL 3.0 and TLS 1.0 connections were vulnerable to some chosen plaintext attacks which allowed man-in-the middle attackers to obtain plaintext HTTP headers on an HTTPS session. This issue is known as the 'BEAST' attack.

CVE-2014-1569

Possible information leak with too-permissive ASN.1 DER decoding of length.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
