1.117.1. RHBA-2011:1016: pam_krb5 bug fix update
An updated pam_krb5 package that fixes various bugs is now available for Red Hat Enterprise Linux 5.
The pam_krb5 package allows applications which use the Pluggable Authentication Modules (PAM) framework to perform password-based authentication using Kerberos 5.
* Previously, multiple authentication attempts may have led to a memory leak when the pam_krb5 module was unloaded. This was caused when the calling application cleaned up the context it used when interacting with the libpam. This has been fixed by preventing the module from being unloaded. (BZ#643962
All users of pam_krb5 are advised to upgrade to this updated package, which resolves these issues.
