APPLE-SA-2003-02-14 Mac OS X 10.2.4 client
Mac OS X 10.2.4 client Software Update is now available. It contains
fixes for
the following potential security issues:
* Sendmail: Fixes CAN-2002-0906 Buffer overflow in Sendmail before
8.12.5, when
configured to use a custom DNS map to query TXT records, could permit a
denial
of service attack and possibly allow execution of arbitrary code. Mac
OS X
10.2.4 contains Sendmail 8.12.6 with the SMRSH fix applied to also
address
CAN-2002-1165 .
* AFP: Fixes CAN-2003-0049 "AFP login permissions for the system
administrator". Provides an option whereby a system administrator may
or may
not be allowed to log in as a user, authenticating via their admin
password.
Previously, administrators could always log in as a user,
authenticating via
their own admin password.
* Classic: Fixes CAN-2003-0088 , where an attacker may change an
environment
variable to create arbitrary files or overwrite existing files, which
could lead
to obtaining elevated privileges. Credit to Dave G. from @stake, Inc.
for
discovering this issue.
* Samba: Previous releases of Mac OS X are not vulnerable to
CAN-2002-1318 , an
issue in Samba's length checking for encrypted password changes. Mac
OS X
currently uses Directory Services for authentication, and does not call
the
vulnerable Samba function. However, to prevent a potential future
exploit via
this function, the patch from Samba 2.2.7 was applied although the
version of
Samba was not changed for this update release. Further information is
available
from: http://samba.org/samba/whatsnew/samba-2.2.7.html
