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).
