Description

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-2013-0213)

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-2013-0214)

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.

After installing this update, the smb service will be restarted automatically.
