The remote Oracle Linux host is missing one or more security updates.
From Red Hat Security Advisory 2008:0890 :
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.
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.
