Moderate: wireshark security update

Synopsis

Moderate: wireshark security update

Type/Severity

Security Advisory: Moderate

Topic

Updated wireshark packages that fix several security issues are now
available for Red Hat Enterprise Linux 3, 4, and 5.

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

Description

Wireshark is a program for monitoring network traffic. Wireshark was
previously known as Ethereal.

Multiple buffer overflow flaws were found in Wireshark. If Wireshark read
a malformed packet off a network, it could crash or, possibly, execute
arbitrary code as the user running Wireshark. (CVE-2008-3146)

Several denial of service flaws were found in Wireshark. Wireshark could
crash or stop responding if it read a malformed packet off a network, or
opened a malformed dump file. (CVE-2008-1070, CVE-2008-1071, CVE-2008-1072,
CVE-2008-1561, CVE-2008-1562, CVE-2008-1563, CVE-2008-3137, CVE-2008-3138,
CVE-2008-3141, CVE-2008-3145, CVE-2008-3932, CVE-2008-3933, CVE-2008-3934)

Additionally, this update changes the default Pluggable Authentication
Modules (PAM) configuration to always prompt for the root password before
each start of Wireshark. This avoids unintentionally running Wireshark with
root privileges.

Users of wireshark should upgrade to these updated packages, which contain
Wireshark version 1.0.3, and resolve these issues.

Solution

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
