Summary
Red Hat Security Advisory: : : : Updated mm packages fix temporary file handling

Notes

Topic
Updated mm packages are now available for Red Hat Linux on IBM iSeries and pSeries systems. These updates address possible vulnerabilities in the way the MM library opens temporary files.
Details
The MM library provides an abstraction layer allowing related processes to share data easily. On systems where shared memory or other inter-process communication mechanisms are not available, the MM library emulates them using temporary files. MM is used in Red Hat Linux to providing shared memory pools to Apache modules. Versions of MM up to and including 1.1.3 open temporary files in an unsafe manner, allowing a malicious local user to cause an application that uses MM to overwrite any file to which it has write access. All users are advised to upgrade to these errata packages, which contain a patched version of MM that is not vulnerable to this issue. Thanks to Marcus Meissner for providing a patch for this issue.

Only those\nRPMs which are currently installed will be updated.  Those RPMs which are\nnot installed but included in the list will not be updated.  Note that you\ncan also use wildcards (*.rpm) if your current directory *only* contains the\ndesired RPMs.\n\nPlease note that this update is also available via Red Hat Network.  Many\npeople find this an easier way to apply updates.  To use Red Hat Network,\nlaunch the Red Hat Update Agent with the following command:\n\nup2date\n\nThis will start an interactive process that will result in the appropriate\nRPMs being upgraded on your system.",
