1.201.1. RHBA-2011:0444: ypserv bug fix update
The Network Information Service (NIS) is a system that provides network information (login names, passwords, home directories, group information) to all of the machines on a network.
* Due to a string concatenation error in the code, running the "yppasswdd" command and using the "-x" option, which instructs yppasswdd to pass data to an external program to update the source files and maps, could have caused garbage characters to be inserted in front of the username, thus causing the output to become unparseable. This has been resolved in this updated package by changing the operation to a string-copy, with the result that the username is no longer corrupted when using the "-x" option. (BZ#688237
All users of ypserv are advised to upgrade to this updated package, which resolves this issue.
