Debian Security Advisory DSA-059-1 securitydebian.org
http://www.debian.org/security/ Wichert Akkerman
June 12, 2001
- ------------------------------------------------------------------------

Package : man-db
Problem type : symlink attack
Debian-specific: no

Luki R. reported a bug in man-db: it did handle nested calls of
drop_effective_privs() and regain_effective_privs() correctly which
would cause it to regain privileges to 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.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.
