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.
