8.190. samba4
Updated samba4 packages that fix one security issue and two bugs are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links associated with each description below.
Samba is an open-source implementation of the Server Message Block (SMB) or Common Internet File System (CIFS) protocol, which allows PC-compatible machines to share files, printers, and other information.
Security Fix
- CVE-2013-4124
- 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.
Note: This issue did not affect the default configuration of the Samba server.
Bug Fixes
- BZ#882338
- 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.
- BZ#911264
- 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.
All samba4 users are advised to upgrade to these updated packages, which contain a backported patch to correct these issues.
