Vulnerability Assessment Details

RHSA-2002-154: mm

Vulnerability Assessment Summary
Check for the version of the mm packages

Detailed Explanation for this Vulnerability Assessment


Updated mm packages are now available for Red Hat Linux Advanced Server.
This update addresses possible vulnerabilities in how the MM library
opens temporary files.

The MM library provides an abstraction layer which permits related processes
to easily share data. On systems where shared memory or other
inter-process communication mechanisms are not available, the MM library
will emulate 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, permiting 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.
