Cyrus SASL vulnerability


Packages

Details

James Ralston discovered that the Cyrus SASL base64 encoding function
could be used unsafely. If a remote attacker sent a specially crafted
request to a service that used SASL, it could lead to a loss of privacy,
or crash the application, resulting in a denial of service.
