Scientific Linux Security Update : samba4 on SL6.x i386/x86_64

This script is Copyright (C) 2013 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

An integer overflow flaw was found in the way Samba handled an
Extended Attribute (EA) list provided by a client. A malicious client
could send a specially crafted EA list that triggered an overflow,
causing the server to loop and reprocess the list using an excessive
amount of memory. (CVE-2013-4124)

Note: This issue did not affect the default configuration of the Samba
server.

This update fixes the following bugs :

- When Samba was installed in the build root directory,
the RPM target might not have existed. Consequently, the
find-debuginfo.sh script did not create symbolic links
for the libwbclient.so.debug module associated with the
target. With this update, the paths to the symbolic
links are relative so that the symbolic links are now
created correctly.

- Previously, the samba4 packages were missing a
dependency for the libreplace.so module which could lead
to installation failures. With this update, the missing
dependency has been added to the dependency list of the
samba4 packages and installation now proceeds as
expected.
