Red Hat Security Advisory 2015-1681-01

Red Hat Security Advisory 2015-1681-01 – OpenStack Object Storage provides object storage in virtual containers, which allows users to store and retrieve files. The service’s distributed architecture supports horizontal scaling; redundancy as failure-proofing is provided through software-based data replication. Because Object Storage supports asynchronous eventual consistency replication, it is well suited to multiple data-center deployment. A flaw was found in openstack-swift where an authenticated user may delete the most recent version of a versioned object regardless of ownership. To exploit this flaw an attacker most know the name of the object and have listing access to the x-versions-location container.

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 does not properly terminate a data structure after a failure to locate a number within a string, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

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 does not properly consider a certain case of multiple realloc operations that restore a memory chunk to its original size, which allows remote attackers to cause a denial of service (incorrect free operation and application crash) via a crafted packet.

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 allows 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.

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 allows remote attackers to cause a denial of service (application crash) via a crafted packet.

CVE-2015-6245

epan/dissectors/packet-gsm_rlcmac.c in the GSM RLC/MAC dissector in Wireshark 1.12.x before 1.12.7 uses incorrect integer data types, which allows remote attackers to cause a denial of service (infinite loop) via a crafted packet.

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 allows remote attackers to cause a denial of service (application crash) via a crafted packet.

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 does not validate a certain offset value, which allows remote attackers to cause a denial of service (infinite loop) via a crafted packet.

CVE-2015-6248

The ptvcursor_add function in the ptvcursor implementation in epan/proto.c in Wireshark 1.12.x before 1.12.7 does not check whether the expected amount of data is available, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.
