A number of bugs were discovered in the NDR parsing support in Samba that is used to decode MS-RPC requests. A remote attacker could send a carefully crafted request that would cause a heap overflow, possibly leading to the ability to execute arbitrary code on the server (CVE-2007-2446). A remote authenticated user could trigger a flaw where unescaped user input parameters were being passed as arguments to /bin/sh (CVE-2007-2447). Finally, on Samba 3.0.23d and higher, when Samba translated SID to/from name using the Samba local list of user and group accounts, a logic error in smbd's internal security stack could result in a transition to the root user id rather than the non-root user (CVE-2007-2444). Updated packages have been patched to prevent these issues.
