Package: libsnmp-base
Version: 5.2.3-1
Severity: critical
Justification: may lead to DoS

I just noticed that somehow the file /usr/share/snmp/mibs/.index had been
created, probably due to the hplip package using SNMP; despite creating a file
dynamically in /usr probably violates FHS, the permissions of the file impose a
security threat:

-rw-rw-rw- 1 root root 2148 Sep 20 17:50 /usr/share/snmp/mibs/.index

Any user may fill this file with arbitrary data and thus get the partition this
directory resides on completely filled. Furthermore it may introduce other
security risks, if the contents of this file is evaluated; but I don't know
anything about the internals of libsnmp and thus cannot say, whether this really
poses a problem.

Regards,
Michael
