Cyrus-SASL: Execution of arbitrary code

Cyrus-SASL: Execution of arbitrary code A buffer overflow in Cyrus-SASL might allow for the execution of arbitrary code in applications or daemons that authenticate using SASL. cyrus-sasl 2009-07-12 2009-07-12 270261 remote 2.1.23 2.1.23

Cyrus-SASL is an implementation of the Simple Authentication and Security Layer.

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.

All Cyrus-SASL users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-libs/cyrus-sasl-2.1.23"
