nss: CVE-2013-5606
Upstream-Status: Backport
the patch comes from:
http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2013-5606
https://bugzilla.mozilla.org/show_bug.cgi?id=910438
http://hg.mozilla.org/projects/nss/rev/d29898e0981c
The CERT_VerifyCert function in lib/certhigh/certvfy.c in
Mozilla Network Security Services (NSS) 3.15 before 3.15.3 provides
an unexpected return value for an incompatible key-usage certificate
when the CERTVerifyLog argument is valid, which might allow remote
attackers to bypass intended access restrictions via a crafted certificate.
