Test Kennung:1.3.6.1.4.1.25623.1.0.150715
Kategorie:Buffer overflow
Titel:Samba 2.0.0 <= 2.2.8 Multiple Vulnerabilities
Zusammenfassung:Samba is prone to multiple vulnerabilities.
Beschreibung:Summary:
Samba is prone to multiple vulnerabilities.

Vulnerability Insight:
- CVE-2003-0196:

A buffer overrun condition exists in the SMB/CIFS packet fragment
re-assembly code in smbd which would allow an attacker to cause smbd
to overwrite arbitrary areas of memory in its own process address
space. This could allow a skilled attacker to inject binary specific
exploit code into smbd.

This version of Samba adds explicit overrun and overflow checks on
fragment re-assembly of SMB/CIFS packets to ensure that only valid
re-assembly is performed by smbd.

In addition, the same checks have been added to the re-assembly
functions in the client code, making it safe for use in other
services.

- CVE-2003-0201:

This vulnerability, if exploited correctly, leads to an anonymous
user gaining root access on a Samba serving system. All versions
of Samba up to and including Samba 2.2.8 are vulnerable. An active
exploit of the bug has been reported in the wild. Alpha versions of
Samba 3.0 and above are *NOT* vulnerable.

Affected Software/OS:
Samba versions 2.0.0 through 2.2.8.

Solution:
Update to version 2.2.8a or later.

CVSS Score:
10.0
