CVE-2016-7176

epan/dissectors/packet-h225.c in the H.225 dissector in Wireshark 2.x before 2.0.6 calls snprintf with one of its input buffers as the output buffer, which allows remote attackers to cause a denial of service (copy overlap and application crash) via a crafted packet.

The wireshark package has been updated to version 2.0.6, which fixes several security issues where a malformed packet trace could cause it to crash, and fixes several other bugs as well. See the release notes for details.

These are all security issues fixed in the wireshark-2.2.2-1.1 package on the GA media of openSUSE Tumbleweed.

Wireshark was updated to version 2.0.12, which brings several new features, enhancements and bug fixes.

These security issues were fixed:

• CVE-2017-7700: In Wireshark the NetScaler file parser could go into an infinite loop, triggered by a malformed capture file. This was addressed in wiretap/netscaler.c by ensuring a nonzero record size (bsc#1033936).
• CVE-2017-7701: In Wireshark the BGP dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-bgp.c by using a different integer data type (bsc#1033937).
• CVE-2017-7702: In Wireshark the WBXML dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-wbxml.c by adding length validation (bsc#1033938).
• CVE-2017-7703: In Wireshark the IMAP dissector could crash, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-imap.c by calculating a line's end correctly (bsc#1033939).
• CVE-2017-7704: In Wireshark the DOF dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-dof.c by using a different integer data type and adjusting a return value (bsc#1033940).
• CVE-2017-7705: In Wireshark the RPC over RDMA dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-rpcrdma.c by correctly checking for going beyond the maximum offset (bsc#1033941).
• CVE-2017-7745: In Wireshark the SIGCOMP dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-sigcomp.c by correcting a memory-size check (bsc#1033942).
• CVE-2017-7746: In Wireshark the SLSK dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-slsk.c by adding checks for the remaining length (bsc#1033943).
• CVE-2017-7747: In Wireshark the PacketBB dissector could crash, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-packetbb.c by restricting additions to the protocol tree (bsc#1033944).
• CVE-2017-7748: In Wireshark the WSP dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-wsp.c by adding a length check (bsc#1033945).
• CVE-2016-7179: Stack-based buffer overflow in epan/dissectors/packet-catapult-dct2000.c in the Catapult DCT2000 dissector in Wireshark allowed remote attackers to cause a denial of service (application crash) via a crafted packet (bsc#998963).
• CVE-2016-9376: In Wireshark 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 (bsc#1010735).
• CVE-2016-9375: In Wireshark 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 (bsc#1010740).
• CVE-2016-9374: In Wireshark 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 (bsc#1010752).
• CVE-2016-9373: In Wireshark 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 (bsc#1010754).
