CVSS v2.0
6.8
Média
| Vetor | AV:N/AC:M/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
Postfix versions prior to 2.5.13
Postfix versions 2.6.x prior to 2.6.10
Postfix versions 2.7.x prior to 2.7.4
Postfix versions 2.8.x prior to 2.8.3
Description
The issue is related to the SMTP server in Postfix when certain Cyrus SASL authentication methods are enabled. It does not create a new server handle after client authentication fails, which allows remote attackers to cause a denial of service or possibly execute arbitrary code via an invalid AUTH command with one method followed by an AUTH command with a different method.
Recommendations
For Postfix versions prior to 2.5.13, update to version 2.5.13 or later.
For Postfix versions 2.6.x prior to 2.6.10, update to version 2.6.10 or later.
For Postfix versions 2.7.x prior to 2.7.4, update to version 2.7.4 or later.
For Postfix versions 2.8.x prior to 2.8.3, update to version 2.8.3 or later.
