Scientific Linux 6.x Moderate Advisory: Postfix TLS Issue Threat

Moderate: postfix security update. Date: Thu, 7 Apr 2011 10:50:59 -0500 Reply-To: Troy Dawson Sender: Security Errata for Scientific Linux From: Troy Dawson Subject: Security ERRATA Moderate: postfix on SL6.x i386/x86_64 Comments: To: "This email address is being protected from spambots. You need JavaScript enabled to view it." MIME-Version: 1.0 Synopsis: Moderate: postfix security update Issue date: 2011-04-06 CVE Names: CVE-2011-0411 It was discovered that Postfix did not flush the received SMTP commands buffer after switching to TLS encryption for an SMTP session. A man-in-the-middle attacker could use this flaw to inject SMTP commands into a victim's session during the plain text phase. This would lead to those commands being processed by Postfix after TLS encryption is enabled, possibly allowing the attacker to steal the victim's mail or authentication credentials. (CVE-2011-0411) After installing this update, the postfix service will be restarted automatically. SL 6.x SRPMS: postfix-2.6.6-2.1.el6_0.src.rpm i386: postfix-2.6.6-2.1.el6_0.i686.rpm postfix-perl-scripts-2.6.6-2.1.el6_0.i686.rpm x86_64: postfix-2.6.6-2.1.el6_0.x86_64.rpm postfix-perl-scripts-2.6.6-2.1.el6_0.x86_64.rpm - Scientific Linux Development Team . The latest postfix enhancement for Scientific Linux mitigates a TLS command injection vulnerability that could potentially enable email unauthorized access..
