RHSA-2005:575 - Security Advisory

Topic

Updated acroread packages that fix a security issue are now available.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

Description

The Adobe Acrobat Reader browser allows for the viewing, distributing, and
printing of documents in portable document format (PDF).

A buffer overflow bug has been found in Adobe Acrobat Reader. It is
possible to execute arbitrary code on a victim's machine if the victim is
tricked into opening a malicious PDF file. The Common Vulnerabilities and
Exposures project has assigned the name CAN-2005-1625 to this issue.

Please note that there is no browser plugin included with the x86_64 Adobe
Acrobat Reader package; Therefore the security impact of this issue on
x86_64 is reduced from "critical" to "important".

Additionally Secunia Research discovered a bug in the way Adobe Acrobat
Reader creates temporary files. When a user opens a document, temporary
files are created which may be world readable, allowing a local user to
view sensitive information. The Common Vulnerabilities and Exposures
project has assigned the name CAN-2005-1841 to this issue.

All users of Acrobat Reader are advised to upgrade to these updated
packages, which contain Acrobat Reader version 7.0.0 and are not vulnerable
to this issue.

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.
