Versions affected: 0.99.6 * Beyond Security discovered that Wireshark could loop excessively while reading a malformed DNP packet. Versions affected: 0.10.12 to 0.99.6 * Stefan Esser discovered a buffer overflow in the SSL dissector. Versions affected: 0.99.0 to 0.99.6 * The ANSI MAP dissector could be susceptible to a buffer overflow on some platforms. (Bug 1844) Versions affected: 0.99.5 to 0.99.6 * The Firebird/Interbase dissector could go into an infinite loop or crash. (Bugs 1931 and 1932) Versions affected: 0.99.6 * The NCP dissector could cause a crash. Versions affected: 0.99.6 * The HTTP dissector could crash on some systems while decoding chunked messages. Versions affected: 0.10.14 to 0.99.6 * The MEGACO dissector could enter a large loop and consume system resources. Versions affected: 0.9.14 to 0.99.6 * The DCP ETSI dissector could enter a large loop and consume system resources. Versions affected: 0.99.6 * Fabiodds discovered a buffer overflow in the iSeries (OS/400) Communication trace file parser. (Bug 1926) Versions affected: 0.99.0 to 0.99.6 * The PPP dissector could overflow a buffer. Versions affected: 0.99.6 * The Bluetooth SDP dissector could go into an infinite loop. Versions affected: 0.99.2 to 0.99.6 * A malformed RPC Portmap packet could cause a crash. (Bug 1998) Versions affected: 0.8.16 to 0.99.6 * The IPv6 dissector could loop excessively. (Bug 2007) Versions affected: 0.99.6 * The USB dissector could loop excessively or crash. (Bugs 2012, 2013, and 2021) Versions affected: 0.99.6 * The SMB dissector could crash. (Bug 2019) Versions affected: 0.99.6 * The RPL dissector could go into an infinite loop. (Bug 2052) Versions affected: 0.9.8 to 0.99.6 * The WiMAX dissector could crash due to unaligned access on some platforms. (Bug 2072) Versions affected: 0.99.6 * The CIP dissector could attempt to allocate a huge amount of memory and crash. Versions affected: 0.9.14 to 0.99.6 Impact It may be possible to make Wireshark or Ethereal crash or use up available memory by injecting a purposefully malformed packet onto the wire or by convincing someone to read a malformed packet trace file. Resolution Upgrade to Wireshark 0.99.7. If are running Wireshark 0.99.6 or Ethereal 0.99.0 or earlier and cannot upgrade, you can work around each of the problems listed above by doing the following: * Disable the HTTP, DCP ETSI, SSL, DHCP/BOOTP, and MMS dissectors. o Select Analyze -> Enabled Protocols... from the menu. o Make sure "ANSI MAP", "BTSDP", "DCP (ETSI)", "DNP 3.0", "FB/IPB GDS DB", "HTTP", "MEGACO", "NCP", "PPP", "SSL" are un-checked. o Click "Save", then click "OK". - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
