Description Arvid Requate

2015-10-14 19:50:37 CEST

Upstream Debian package version 0.2.0-8+deb7u1 fixes this issue:

* A remotely triggerable use-after-free vulnerability was found in rpcbind, a server that converts RPC program numbers into universal addresses. A remote attacker can take advantage of this flaw to mount a denial of service (rpcbind crash) (CVE-2015-7236)

nfs-common depends on this process in UCS 4.0-x.

UCS 4.0-3 is still maintained, therefore this should be "version: [3,4]"
