Описание
Multiple memory leaks in the x11_init_protocol function in epan/dissectors/packet-x11.c in the X11 dissector in Wireshark 1.10.x before 1.10.14 and 1.12.x before 1.12.5 allow remote attackers to cause a denial of service (memory consumption) via a crafted packet.
A flaw was found in X11 dissector of wireshark of which an attacker could make wireshark consume excessive CPU resources which could make system unresponsive by injecting specially crafted packet onto the wire or by convincing wireshark user to read malformed packet trace file.
Меры по смягчению последствий
This flaw can be mitigated in wireshark by disabling the X11 protocol dissector. In wireshark GUI application click on Analyze->Enabled Protocols and search for "X11" and disable in. When using "tshark", the text interface, create a file called "disabled_protos" in the preferences folder (normally .wireshark folder in the home directory of the user running wireshark) and add "X11" to it. This should disable the X11 protocol.
