CONECTIVA LINUX SECURITY ANNOUNCEMENT
PACKAGE : samba
SUMMARY : Multiple potential buffer overruns
DATE : 2004-07-22 13:01:00
ID : CLA-2004:851
RELEVANT RELEASES : 10
DESCRIPTION
Samba[1] provides SMB/CIFS services (such as file and printer
sharing) used by clients compatible with Microsoft Windows(TM).
Evgeny Demidov noticed that the internal routine used by the
Samba Web Administration Tool (SWAT) to decode the base64 data
during HTTP basic authentication is subject[2] to a buffer overrun
caused by an invalid base64 character. This same code is used
internally to decode the sambaMungedDial attribute value when using
the ldapsam passdb backend and to decode input given to the
ntlm_auth tool.
Another buffer overrun problem[3] has been located in the code
used to support the ‘mangling method = hash’ smb.conf option.
Please be aware that the default setting for this parameter is
‘mangling method
- hash2′ and therefore not vulnerable.
Conectiva Linux versions 8 and 9 are also vulnerable to the
second problem and a specific announcement for it is pending.
SOLUTION
It is recommended that all samba users upgrade their packages. This
update will automatically restart the service if it is already
running.
