1.32.1. RHBA-2010:0151: bug fix update
The cyrus-sasl packages contain the Cyrus implementation of SASL. SASL is the Simple Authentication and Security Layer, a method for adding authentication support to connection-based protocols.
* multithreaded programs which used the Cyrus SASL libraries could have become unresponsive after attempting to perform authentication routines. This was caused by a failure to release a mutex lock on a data structure in the Cyrus SASL code, which resulted in a race condition, thus causing the program using the library to hang. This race condition has been fixed so that it is thread-safe in this update. (
BZ#568084)
All users of cyrus-sasl are advised to upgrade to these updated packages, which resolve this issue.
