Topic: Updated ypserv packages which fix a memory leak are now available for Red Hat Linux 7.x and 6.2. 2. Relevant releases/architectures: Red Hat Linux 6.2 - alpha, i386, sparc Red Hat Linux 7.0 - alpha, i386 Red Hat Linux 7.1 - alpha, i386, ia64 Red Hat Linux 7.2 - i386, ia64 Red Hat Linux 7.3 - i386 3. Problem description: ypserv is an NIS authentication server. ypserv versions before 2.5 contain a memory leak that can be triggered remotely. When someone requests a map that doesn't exist, a previous mapname may be leaked. This happens, for instance, if you run "ypmatch foo aaaaaaaaaaaaaaaaaaaa". Repeated runs will result in the yp server using more and more memory, and running more slowly. It could also result in ypserv being killed due to the system being out of memory. This errata updates Red Hat Linux 7.x to ypserv version 2.5 which doesn't have the memory leak, and updates Red Hat Linux 6.x to a patched version of ypserv that doesn't have the memory leak. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5.
