Description:
Two vulnerabilities have been reported in Samba, potentially allowing malicious people to compromise a vulnerability system.
1) The vulnerability is caused due to a boundary error when decoding base64 data during HTTP basic authentication. This can potentially be exploited to cause a buffer overflow.
2) The vulnerability is caused due to a boundary error in the code used to handle "mangling method = hash". This can potentially be exploited to cause a buffer overflow.
The default setting in Samba 3 and later is "mangling method = hash2". A default installation of Samba 3 is therefore not vulnerable to issue 2.
Issue 1 affects Samba 3.0.2 to 3.0.4.
Issue 2 affects Samba 3.0.0 to 3.0.4 and Samba 2.2.9 and prior.
Solution:
Both issues have been fixed in Samba version 3.0.5 and issue 2 has been fixed in Samba version 2.2.10.
