RHBA-2013:0660 - ypserv bug fix update

Synopsis

ypserv bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated ypserv packages that fix one bug are now available for Red Hat Enterprise Linux 5.

Description

The ypserv packages provide the Network Information Service (NIS) server. NIS is a system that provides network information such as login names, passwords, home directories, and group information to all the machines on a network.

This update fixes the following bug:

  • Previously, the ypserv utility allocated large amounts of virtual memory when parsing XDR requests, but failed to free that memory if the request was not parsed successfully. Consequently, memory leaks occurred. With this update, a patch has been provided to free the already allocated memory when the parsing of a request fails and, as a result, memory leaks no longer occur. (BZ#920111)

Users of ypserv 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.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258
