Synopsis :

The remote openSUSE host is missing a security update.

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).
