The remote host is missing updates announced in
advisory RHSA-2011:0369.
Wireshark is a program for monitoring network traffic. Wireshark was
previously known as Ethereal.
A heap-based buffer overflow flaw was found in the Wireshark MAC-LTE
dissector. If Wireshark read a malformed packet off a network or opened a
malicious dump file, it could crash or, possibly, execute arbitrary code as
the user running Wireshark. (CVE-2011-0444)
A heap-based buffer overflow flaw was found in the way Wireshark processed
signaling traces generated by the Gammu utility on Nokia DCT3 phones
running in Netmonitor mode. If Wireshark opened a specially-crafted capture
file, it could crash or, possibly, execute arbitrary code as the user
running Wireshark. (CVE-2011-0713)
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 malicious dump file. (CVE-2011-0538, CVE-2011-1139, CVE-2011-1140,
CVE-2011-1141)
Users of Wireshark should upgrade to these updated packages, which contain
Wireshark version 1.2.15, and resolve these issues. All running instances
of Wireshark must be restarted for the update to take effect.
