Vulnerability Assessment Details

[DSA059] DSA-059-1 man-db

Vulnerability Assessment Summary
DSA-059-1 man-db

Detailed Explanation for this Vulnerability Assessment

Luki R. reported a bug in man-db: it did not handle nested calls of
drop_effective_privs() and regain_effective_privs() correctly which
would cause it to regain rights too early. This could be abused
to make man create files as user man.

This has been fixed in version 2.3.16-4, and we recommend that you
upgrade your man-db package immediately. If you use suidmanager you
can also use that to make sure man and mandb are not installed suid
which protects you from this problem. This can be done with the
following commands:

suidregister /usr/lib/man-db/man root root 0755
suidregister /usr/lib/man-db/mandb root root 0755

Of course even when using suidmanager an upgrade is still strongly
recommended.
