DescriptionUpdated 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.
SolutionUpdate the affected wireshark and / or wireshark-gnome packages.
