Description

This updates the pam_krb5 package from version 2.3.2 to 2.3.5, fixing CVE-2009-1384: in certain configurations, the password prompt could vary depending on whether or not the user account was known to the system or the KDC. It also fixes a bug which prevented password change attempts from working if the KDC denied requests for password-changing credentials with settings which would be used for login credentials, and makes the '-n' option for the 'afs5log' command work as advertised.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
