Synopsis: Critical: samba security update
Issue date: 2007-05-14
CVE Names: CVE-2007-2446 CVE-2007-2447

Various bugs were found in NDR parsing, used to decode MS-RPC requests in
Samba. A remote attacker could have sent carefully crafted requests
causing a heap overflow, which may have led to the ability to execute
arbitrary code on the server. (CVE-2007-2446)

Unescaped user input parameters were being passed as arguments to /bin/sh.
A remote, authenticated, user could have triggered this flaw and executed
arbitrary code on the server. Additionally on Scientific Linux 5 this
flaw could be triggered by a remote unauthenticated user if
Samba was configured to use the non-default "username map script" option.
(CVE-2007-2447)
