                        SuSE Security Announcement

        Package: util < 2.10f
        Date:    Thu Feb 10 20:03:43 CET 2000

        Affected SuSE versions: all
        Vulnerability Type:     (unlikely) local root compromise
        SuSE default package:   yes
        Other affected systems: all linux systems using util < 2.10f
______________________________________________________________________________

A security hole was discovered in the package mentioned above.
Please update it as soon as possible or disable the service if you are using
this software on your SuSE Linux installation(s).

Other Linux distributions or operating systems might be affected as
well, please contact your vendor for information about this issue.

Please note that we provide this information on an "as-is" basis only.
There is no warranty whatsoever and no liability for any direct, indirect or
incidental damage arising from this information or the installation of
the update package.
_____________________________________________________________________________

1. Problem Description

  The mount/umount command doesn't do proper bounds checking on user input.

2. Impact

  If an attacker executes mount/umount with a long relative pathname, it
  will overwrite dynamic allocated memory of the realpath function.
  It is possible that an attacker could gain root privileges by modifying
  the heap data, however we were not able to exploit it.

3. Solution

  Update the package from our FTP server or remove the suid bits.
