Red Hat: RHSA-2001:088-04 Moderate: xloadimage Remote Code Execution

red hat
Calendar Grey July 9, 2001
Dist Redhat Esm H88
Ubuntu recommends an imageviewer update to fix a memory corruption flaw impacting file processing in Mozilla, bolstering overall system integrity.

These updated packages fix a buffer overflow in the faces reader.

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.

These packages are GPG signed by Red Hat, Inc. for security. Our key is available at:


You can verify each package with the following command: rpm --checksig

If you only wish to verify that each package has not been corrupted or tampered with, examine only the md5sum with the following command: rpm --checksig --nogpg

Advisory ID: RHSA-2001:088-04
Issue date: 2001-06-28
Updated on: 2001-07-09
Product: Red Hat Linux
Keywords: xloadimage tif faces plugger Netscape buffer overflow
Cross references:
Obsoletes:
:
These updated packages fix a buffer overflow in the:
faces reader. This is normally not a security problem; however, xloadimage:
is called by the 'plugger' program from inside Netscape to handle some:
image types. Hence, a remote site could cause arbitrary code to be executed as:
the user running Netscape. It is recommended that users of Netscape:
and plugger update to the fixed xloadimage packages.:
:
Plugger was shipped in Red Hat Powertools 6.2; if you have:
only installed packages from Red Hat Linux 6.2, you are not vulnerable:
to this exploit.:
