Security Fixes
- CVE-2013-0213
- It was discovered that the Samba Web Administration Tool (SWAT) did not protect against being opened in a web page frame. A remote attacker could possibly use this flaw to conduct a clickjacking attack against SWAT users or users with an active SWAT session.
- CVE-2013-0214
- A flaw was found in the Cross-Site Request Forgery (CSRF) protection mechanism implemented in SWAT. An attacker with the knowledge of a victim's password could use this flaw to bypass CSRF protections and conduct a CSRF attack against the victim SWAT user.
- 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 Fix
- BZ#1132425
- Dropbox is a directory with permission 0733. Previously, when the user was trying to store a file in a dropbox directory, the file could not be created. As a consequence, an ACCESS_DENIED error was returned. The permissions to such a directory are now correctly processed by the smbd daemon, and the user can save files to a dropbox directory again.
