Description GLSAMaker/CVETool Bot gentoo-dev 2018-03-13 12:24:50 UTC 
CVE-2018-1057 (https://nvd.nist.gov/vuln/detail/CVE-2018-1057):
  On a Samba 4 AD DC the LDAP server in all versions of Samba from 4.0.0
  onwards incorrectly validates permissions to modify passwords over LDAP
  allowing authenticated users to change any other users passwords, including
  administrative users.

CVE-2018-1050 (https://nvd.nist.gov/vuln/detail/CVE-2018-1050):
  A null pointer indirection in the printer server process may lead to denial
  of service.
Comment 1 Thomas Deutschmann (RETIRED) gentoo-dev 2018-03-13 12:35:22 UTC 
CVE-2018-1057 requires net-fs/samba[addc] and can be mitigated by revoking the change passwords right for everyone from all user objects (including computers) in the directory. Note that this will prevent users from being able to change their own expired passwords, so the maximum password age should be set to a value that prevents user passwords from expiring while the workaround is in place.

@arches: Test suite will most likely fail. Just do a compile check.

actually, since hppa has no keywords we don't need to block security. I'll just stabilize this at some point later.

hppa has keywords on 4.5.16 and is stable on 4.2.14.

hppa is now exp.

@maintainer(s), please clean vulnerable.
