Samba 2.2.2 <= 2.2.6 Vulnerability (CVE-2003-0085)

Samba is prone to a buffer overflow vulnerability.

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 attach 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. All versions of Samba between 2.2.2 to 2.2.6 inclusive are vulnerable to this problem. This version of Samba 2.2.7 contains a fix for this problem. Earlier versions of Samba are not vulnerable. There is no known exploit or exploit code for this vulnerability, it was discovered by a code audit by Debian Samba maintainers.

Samba versions 2.2.2 through 2.2.6.

Checks if a vulnerable version is present on the target host.

Update to version 2.2.7a or later.
