medium Nessus Plugin ID 61010
Language:
Synopsis
The remote Scientific Linux host is missing one or more security updates.Description
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)
It was discovered that Postfix did not properly check the permissions of users' mailbox files. A local attacker able to create files in the mail spool directory could use this flaw to create mailbox files for other local users, and be able to read mail delivered to those users.
(CVE-2008-2937)
After installing this update, the postfix service will be restarted automatically.
Solution
Update the affected postfix and / or postfix-pflogsumm packages.See Also
