| Descripción: | Description:
The remote host is missing updates announced in
advisory RHSA-2007:0354.
Samba provides file and printer sharing services to SMB/CIFS clients.
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 Red Hat Enterprise Linux 5
only, 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)
Users of Samba should upgrade to these packages, which contain backported
patches to correct these issues. After upgrading, Samba should be
restarted using service smb restart
On Red Hat Enterprise Linux 5 the impact of these issues is reduced as
Samba is constrained by the default SELinux targeted policy.
Red Hat would like to thank the Samba developers, TippingPoint, and
iDefense for reporting these issues.
Solution:
