Fedora Legacy Update Advisory
Synopsis: Updated metamail resolves security vulnerability
Advisory ID: FLSA:1305
Issue date: 2004-05-18
Product: Red Hat Linux
Keywords: Security
Cross references: https://bugzilla.fedora.us/show_bug.cgi?id=1305
CVE Names: CAN-2004-0104 CAN-2004-0105
- -----------------------------------------------------------------------
- ---------------------------------------------------------------------
1. Topic:
Updated metamail packages that fix a number of vulnerabilities are now
available.
2. Relevent releases/architectures:
Red Hat Linux 7.2 - i386
Red Hat Linux 7.3 - i386
3. Problem description:
Metamail is a system for handling multimedia mail.
Ulf Harnhammar discovered two integer overflow bugs and two buffer overflow
bugs in versions of Metamail up to and including 2.7. An attacker could
create a carefully-crafted message such that when it is opened by a victim
and parsed through Metamail, it runs arbitrary code as the victim. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the names CAN-2004-0104 and CAN-2004-0105 to these issues.
Users of Red Hat Linux 7.2 and 7.3 are advised to upgrade to these erratum
packages, which contain a backported security patch and are not vulnerable
to these issues. Please note that Red Hat Linux 8 or newer does not
contain Metamail and is therefore not vulnerable to these issues.
Red Hat would like to thank Michal Jaegermann for notification of this
issue, and Ulf Harnhammar for the patch
for these issues.
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 yum and apt. Many
people find this an easier way to apply updates. To use yum issue:
yum update
or to use apt:
apt-get update; apt-get upgrade
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system. This assumes that you have yum or
apt-get configured for obtaining Fedora Legacy content. Please visit
http://www fedoralegacy.org/docs for directions on how to configure yum
and apt-get.
