Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200907-09
(Cyrus-SASL: Execution of arbitrary code)

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

Impact :

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.

Workaround :

There is no known workaround at this time.
