Last modified: 2017-06-28 15:33:30 CEST
1.12.1+g01b65bf-4+deb8u11 fixes: * In Wireshark 2.2.0 to 2.2.3 and 2.0.0 to 2.0.9, the ASTERIX dissector could go into an infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-asterix.c by changing a data type to avoid an integer overflow. (CVE-2017-5596) * In Wireshark 2.2.0 to 2.2.3 and 2.0.0 to 2.0.9, the DHCPv6 dissector could go into a large loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-dhcpv6.c by changing a data type to avoid an integer overflow. (CVE-2017-5597) * In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is a Netscaler file parser infinite loop, triggered by a malformed capture file. This was addressed in wiretap/netscaler.c by changing the restrictions on file size. (CVE-2017-6467) * In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is a NetScaler file parser crash, triggered by a malformed capture file. This was addressed in wiretap/netscaler.c by validating the relationship between pages and records. (CVE-2017-6468) * In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is an LDSS dissector crash, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-ldss.c by ensuring that memory is allocated for a certain data structure. (CVE-2017-6469) * In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is an IAX2 infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-iax2.c by constraining packet lateness. (CVE-2017-6470) * In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is a WSP infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-wsp.c by validating the capability length. (CVE-2017-6471) * In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is an RTMPT dissector infinite loop, triggered by packet injection or a malformed capture file. This was addressed in epan/dissectors/packet-rtmpt.c by properly incrementing a certain sequence value. (CVE-2017-6472) * In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is a K12 file parser crash, triggered by a malformed capture file. This was addressed in wiretap/k12.c by validating the relationships between lengths and offsets. (CVE-2017-6473) * In Wireshark 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10, there is a NetScaler file parser infinite loop, triggered by a malformed capture file. This was addressed in wiretap/netscaler.c by validating record sizes. (CVE-2017-6474)
