Ärende: [RHSA-2002:153-07] Updated mm packages fix temporary file handling ------------------------------------------------------------ From: bugzilla@redhat.com To: redhat-watch-list@redhat.com, redhat-announce-list@redhat.com Cc: bugtraq@securityfocus.com Message-ID: <200207310854.g6V8so602492@porkchop.devel.redhat.com> --------------------------------------------------------------------- Red Hat, Inc. Red Hat Security Advisory Synopsis: Updated mm packages fix temporary file handling Advisory ID: RHSA-2002:153-07 Issue date: 2002-07-24 Updated on: 2002-07-30 Product: Red Hat Linux Keywords: mm temporary file Cross references: Obsoletes: CVE Names: CAN-2002-0658 --------------------------------------------------------------------- 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 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 6.
