Slackware New Samba packages are available for Slackware 8.1 and -current to fix a security problem and provide other bugfixes and improvements.

New Samba packages are available for Slackware 8.1 and -current
to fix a security problem and provide other bugfixes and improvements.
Here are the details from the Slackware 8.1 ChangeLog:

----------------------------
Wed Nov 20 16:51:23 PST 2002
patches/packages/samba-2.2.7-i386-1.tgz:  Upgraded to samba-2.2.7.
  Some details (based on the WHATSNEW.txt file included in samba-2.2.7):
    This fixes a security hole discovered in versions 2.2.2 through 2.2.6 of
    Samba that could potentially allow an attacker to gain root access
    on the target machine.  The word "potentially" is used because there
    is no known exploit of this bug, and the Samba Team has not been able to
    craft one ourselves. However, the seriousness of the problem warrants
    this immediate 2.2.7 release.  There was a bug in the length checking for
    encrypted password change requests from clients. A client could potentially
    send an encrypted password, which, when decrypted with the old hashed
    password could be used as a buffer overrun attack on the stack of smbd. The
    attack would have to be crafted such that converting a DOS codepage string
    to little endian UCS2 unicode would translate into an executable block of
    code.  Thanks to Steve Langasek <vorlon@debian.org> and Eloy Paris
    <peloy@debian.org> for bringing this vulnerability to our notice.
  (* Security fix *)
