Debian DSA-1291-1 : samba - several vulnerabilities
critical Nessus Plugin ID 25228
Synopsis
The remote Debian host is missing a security-related update.Description
Several issues have been identified in Samba, the SMB/CIFS file- and print-server implementation for GNU/Linux.- CVE-2007-2444 When translating SIDs to/from names using Samba local list of user and group accounts, a logic error in the smbd daemon's internal security stack may result in a transition to the root user id rather than the non-root user. The user is then able to temporarily issue SMB/CIFS protocol operations as the root user. This window of opportunity may allow the attacker to establish addition means of gaining root access to the server.
- CVE-2007-2446 Various bugs in Samba's NDR parsing can allow a user to send specially crafted MS-RPC requests that will overwrite the heap space with user defined data.
- CVE-2007-2447 Unescaped user input parameters are passed as arguments to /bin/sh allowing for remote command execution.
Solution
Upgrade the samba package.For the stable distribution (etch), these problems have been fixed in version 3.0.24-6etch1.
For the testing and unstable distributions (lenny and sid, respectively), these problems have been fixed in version 3.0.25-1.
