---------------------------------------------------------------------
1. Topic:
Updated mm packages are now available for Red Hat Linux 7, 7.1, 7.2, and
7.3. These updates address possible vulnerabilities in how the MM library
opens temporary files.
2. Relevant releases/architectures:
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:
The MM library provides an abstraction layer which allows 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=20
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 which 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.
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. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
59504 - *-config scripts suggests bad CFLAGS
68895 - mm not compiled to use SysV shared memory or semaphores
68896 - mm doesn't change ownership properly of SysV semaphores
