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_at_debian.org> and Eloy Paris
<peloy_at_debian.org> for bringing this vulnerability to our notice.
