|Bugzilla:||699035: CVE-2011-1720 postfix (smtpd): Crash due to improper management of SASL handlers for SMTP sessions|
The MITRE CVE dictionary describes this issue as:
The SMTP server in Postfix before 2.5.13, 2.6.x before 2.6.10, 2.7.x before 2.7.4, and 2.8.x before 2.8.3, when certain Cyrus SASL authentication methods are enabled, does not create a new server handle after client authentication fails, which allows remote attackers to cause a denial of service (heap memory corruption and daemon crash) or possibly execute arbitrary code via an invalid AUTH command with one method followed by an AUTH command with a different method.
