Summary:
slocate is susceptible to a local database corruption vulnerability. This
issue is due to a failure of the application to handle unexpected directory
and filename input.
This issue presents itself when the affected utility attempts to index
specially crafted directory structures. The utility fails to handle the
directory structure, and fails to complete the indexing process.
This vulnerability allows local attackers to cause the premature failure of
the index process, resulting in an incomplete database. If the database is
used in further security, backup, or other critical functions, incomplete
data may result in the failure of services dependent on it.
This issue is reported in version 2.7 of slocate, but other versions may
also be affected.
Reproducible: Always

I find this one rather lame.
A local user would create database structures (which would trace the fault back
to him) just to interrupt the indexing process, resulting in a partial DoS of
the slocate facility... "If the database is used in further security, backup, or
other critical functions, incomplete data may result in the failure of services
dependent on it.". Yeah right.
I guess we can fix it... but the security implication doesn't seem that obvious
to me.
Concur with koon, fail to see any security impact from this bug. A user may be
able to cause a minor annoyance that can easily be tracked down and the user
held responsible.
Reassigning to base-system who can decide how to deal with it.
grabbed patch from Fedora and added to 2.7-r8
