Description: wireshark was updated to version 1.12.8 to fix ten security issues. These security issues were fixed: - CVE-2015-6247: The dissect_openflow_tablemod_v5 function in epan/dissectors/packet-openflow_v5.c in the OpenFlow dissector in Wireshark 1.12.x before 1.12.7 did not validate a certain offset value, which allowed remote attackers to cause a denial of service (infinite loop) via a crafted packet (bsc#941500). - CVE-2015-6246: The dissect_wa_payload function in epan/dissectors/packet-waveagent.c in the WaveAgent dissector in Wireshark 1.12.x before 1.12.7 mishandles large tag values, which allowed remote attackers to cause a denial of service (application crash) via a crafted packet (bsc#941500). - CVE-2015-6245: epan/dissectors/packet-gsm_rlcmac.c in the GSM RLC/MAC dissector in Wireshark 1.12.x before 1.12.7 used incorrect integer data types, which allowed remote attackers to cause a denial of service (infinite loop) via a crafted packet (bsc#941500). - CVE-2015-6244: The dissect_zbee_secure function in epan/dissectors/packet-zbee-security.c in the ZigBee dissector in Wireshark 1.12.x before 1.12.7 improperly relies on length fields contained in packet data, which allowed remote attackers to cause a denial of service (application crash) via a crafted packet (bsc#941500). - CVE-2015-6243: The dissector-table implementation in epan/packet.c in Wireshark 1.12.x before 1.12.7 mishandles table searches for empty strings, which allowed remote attackers to cause a denial of service (application crash) via a crafted packet, related to the (1) dissector_get_string_handle and (2) dissector_get_default_string_handle functions (bsc#941500). - CVE-2015-6242: The wmem_block_split_free_chunk function in epan/wmem/wmem_allocator_block.c in the wmem block allocator in the memory manager in Wireshark 1.12.x before 1.12.7 did not properly consider a certain case of multiple realloc operations that restore a memory chunk to its original size, which allowed remote attackers to cause a denial of service (incorrect free operation and application crash) via a crafted packet (bsc#941500). - CVE-2015-6241: The proto_tree_add_bytes_item function in epan/proto.c in the protocol-tree implementation in Wireshark 1.12.x before 1.12.7 did not properly terminate a data structure after a failure to locate a number within a string, which allowed remote attackers to cause a denial of service (application crash) via a crafted packet (bsc#941500). - CVE-2015-7830: pcapng file parser could crash while copying an interface filter (bsc#950437). - CVE-2015-6249: The dissect_wccp2r1_address_table_info function in epan/dissectors/packet-wccp.c in the WCCP dissector in Wireshark 1.12.x before 1.12.7 did not prevent the conflicting use of a table for both IPv4 and IPv6 addresses, which allowed remote attackers to cause a denial of service (application crash) via a crafted packet (bsc#941500). - CVE-2015-6248: The ptvcursor_add function in the ptvcursor implementation in epan/proto.c in Wireshark 1.12.x before 1.12.7 did not check whether the expected amount of data is available, which allowed remote attackers to cause a denial of service (application crash) via a crafted packet (bsc#941500).
