The most popular and widely used network protocol analyzer Wireshark released a new version Wireshark 2.6.5, that comes with the fix for a number of security vulnerabilities that could crash Wireshark by injecting a malformed packet or reading malformed packet trace file.
wnpa-sec-2018-51 – The Wireshark dissection engine could crash.
wnpa-sec-2018-52 – The DCOM dissector could crash.
wnpa-sec-2018-53 – The LBMPDM dissector could crash.
wnpa-sec-2018-54 – The MMSE dissector could go into an infinite loop.
wnpa-sec-2018-55 – The IxVeriWave file parser could crash.
wnpa-sec-2018-56 – The PVFS dissector could crash.
All these vulnerabilities could be exploited by the attacker injecting a malformed packet or by reading a malformed packet trace file. These vulnerabilities affected the following Wireshark versions 2.6.0 to 2.6.4, 2.4.0 to 2.4.10, fixed with 2.6.5, 2.4.11 or later.
wnpa-sec-2018-57 – The ZigBee ZCL dissector could crash. Affected version 2.6.0 to 2.6.4, fixed with 2.6.5.
