Description Arvid Requate

Upstream Debian package has bee updated to version 2:3.26-1+debu8u2 which fixes:

* Out-of-bounds write in Base64 encoding. This can trigger a crash (denial of service) and might be exploitable for code execution (CVE-2017-5461)

* A flaw in DRBG number generation where the internal state V does not correctly carry bits over (CVE-2017-5462)

* Null pointer dereference vulnerability in NSS since 3.24.0 was found when server receives empty SSLv2 messages resulting into denial of service by remote attacker (CVE-2017-7502)

I've installed univention-java and updated.

* Package imported and built in errata4.2-0
* I've moved and updated the advisory to errata4.2-1
* Advisory content ok (magic, looks like collected from two DLAs)
* Package update ok (libnss3)

Reopen: The package is not shown in errata4.2-0 by repo_stat.py
