RHBA-2012:1495 - cyrus-sasl bug fix update

Synopsis

cyrus-sasl bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated cyrus-sasl packages that fix a bug are now available for Red Hat Enterprise Linux 6.

Description

The cyrus-sasl packages contain the Cyrus implementation of Simple Authentication and Security Layer (SASL). SASL is a method for adding authentication support to connection-based protocols.

This update fixes the following bug:

  • Previously, the GSSAPI plug-in kept credential handles open the whole time a client was connected. These handles hold a pointer to a Kerberos replay cache structure. When the replay cache is a file, that structure includes an open file descriptor. When too many clients were using GSSAPI, the server could run out of file handles. Consequently, the client could become unresponsive until restarted. With this update, a GSSAPI credential handle is closed immediately after the plug-in gets the security context, thus preventing this bug. (BZ#878357)

Users of cyrus-sasl are advised to upgrade to these updated packages, which fix this bug.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.
