Debian DSA-2109-1 : samba - buffer overflow

high Nessus Plugin ID 49275


New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security-related update.


A vulnerability has been discovered in samba, a SMB/CIFS file, print, and login server for Unix.

The sid_parse() function does not correctly check its input lengths when reading a binary representation of a Windows SID (Security ID).
This allows a malicious client to send a sid that can overflow the stack variable that is being used to store the SID in the Samba smbd server. (CVE-2010-3069 )


Upgrade the samba packages. The packages for the mips architecture are not included in this upgrade. They will be released as soon as they become available.

For the stable distribution (lenny), this problem has been fixed in version 3.2.5-4lenny13.
