James Ralston reported that in certain situations, Cyrus-SASL does not
|
|
|
|
|
properly terminate strings which can result in buffer overflows when
|
|
|
|
|
performing Base64 encoding.

|
|
A remote unauthenticated user might send specially crafted packets to a
|
|
|
|
|
daemon using Cyrus-SASL, possibly resulting in the execution of
|
|
|
|
|
arbitrary code with the privileges of the user running the daemon or a
|
|
|
|
|
Denial of Service.

There is no known workaround at this time.
