New Wireshark packages that fix various security vulnerabilities and functionality bugs are now available for CentOS Linux 4. Wireshark was previously known as Ethereal. This update has been rated as having low security impact by the CentOS Security Response Team.
Wireshark is a program for monitoring network traffic. Several denial of service bugs were found in Wireshark's HTTP, iSeries, DCP ETSI, SSL, MMS, DHCP and BOOTP protocol dissectors. It was possible for Wireshark to crash or stop responding if it read a malformed packet off the network. (CVE-2007-3389, CVE-2007-3390, CVE-2007-3391, CVE-2007-3392, CVE-2007-3393) Wireshark would interpret certain completion codes incorrectly when dissecting IPMI traffic. Additionally, IPMI 2.0 packets would be reported as malformed IPMI traffic. Users of Wireshark should upgrade to these updated packages containing Wireshark version 0.99.6, which correct these issues.
