The remote Scientific Linux host is missing one or more security
A heap-based buffer overflow flaw was found in the way Wireshark
handled Endace ERF (Extensible Record Format) capture files. If
Wireshark opened a specially- crafted ERF capture file, it could crash
or, possibly, execute arbitrary code as the user running Wireshark.
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-2011-1958,
CVE-2011-1959, CVE-2011-2175, CVE-2011-2698, CVE-2012-0041,
CVE-2012-0042, CVE-2012-0066, CVE-2012-0067, CVE-2012-4285,
CVE-2012-4289, CVE-2012-4290, CVE-2012-4291)
This update also fixes the following bugs :
- When Wireshark starts with the X11 protocol being
tunneled through an SSH connection, it automatically
prepares its capture filter to omit the SSH packets. If
the SSH connection was to a link-local IPv6 address
including an interface name (for example ssh -X
[ipv6addr]%eth0), Wireshark parsed this address
erroneously, constructed an incorrect capture filter and
refused to capture packets. The 'Invalid capture filter'
message was displayed. With this update, parsing of
link-local IPv6 addresses is fixed and Wireshark
correctly prepares a capture filter to omit SSH packets
over a link-local IPv6 connection.
- Previously, Wireshark's column editing dialog malformed
column names when they were selected. With this update,
the dialog is fixed and no longer breaks column names.
- Previously, TShark, the console packet analyzer, did not
properly analyze the exit code of Dumpcap, Wireshark's
packet capturing back end. As a result, TShark returned
exit code 0 when Dumpcap failed to parse its
command-line arguments. In this update, TShark correctly
propagates the Dumpcap exit code and returns a non-zero
exit code when Dumpcap fails.
- Previously, the TShark '-s' (snapshot length) option
worked only for a value greater than 68 bytes. If a
lower value was specified, TShark captured just 68 bytes
of incoming packets. With this update, the '-s' option
is fixed and sizes lower than 68 bytes work as expected.
This update also adds the following enhancement :
- In this update, support for the 'NetDump' protocol was
All running instances of Wireshark must be restarted for the update to
