Arch Linux Security Advisory ASA-201611-23 ========================================== Severity: High Date : 2016-11-24 CVE-ID : CVE-2016-9373 CVE-2016-9374 CVE-2016-9375 CVE-2016-9376 Package : wireshark-gtk Type : multiple issues Remote : Yes Link : https://wiki.archlinux.org/index.php/CVE Summary ======= The package wireshark-gtk before version 2.2.2-1 is vulnerable to multiple issues including arbitrary code execution and denial of service. Resolution ========== Upgrade to 2.2.2-1. # pacman -Syu "wireshark-gtk>=2.2.2-1" The problems have been fixed upstream in version 2.2.2. Workaround ========== None. Description =========== - CVE-2016-9373 (arbitrary code execution) In Wireshark 2.2.0 to 2.2.1 and 2.0.0 to 2.0.7, the DCERPC dissector could crash with a use-after-free, triggered by network traffic or a capture file. This was addressed in epan/dissectors/packet-dcerpc-nt.c and epan/dissectors/packet-dcerpc-spoolss.c by using the wmem file scope for private strings. - CVE-2016-9374 (denial of service) In Wireshark 2.2.0 to 2.2.1 and 2.0.0 to 2.0.7, the AllJoyn dissector could crash with a buffer over-read, triggered by network traffic or a capture file. This was addressed in epan/dissectors/packet-alljoyn.c by ensuring that a length variable properly tracked the state of a signature variable. - CVE-2016-9375 (denial of service) In Wireshark 2.2.0 to 2.2.1 and 2.0.0 to 2.0.7, the DTN dissector could go into an infinite loop, triggered by network traffic or a capture file. This was addressed in epan/dissectors/packet-dtn.c by checking whether SDNV evaluation was successful. - CVE-2016-9376 (denial of service) In Wireshark 2.2.0 to 2.2.1 and 2.0.0 to 2.0.7, the OpenFlow dissector could crash with memory exhaustion, triggered by network traffic or a capture file. This was addressed in epan/dissectors/packet- openflow_v5.c by ensuring that certain length values were sufficiently large. Impact ====== A remote attacker is able to execute arbitrary code or perform a denial of service attack via malicious network traffic.
