[Security] April 3 2015 - 6 New CVEs affect Wireshark

[Thomas Ward]

There are 6 new CVEs which impact Wireshark in Utopic. (Three of these also affect Trusty)

------

CVE-2015-2187: (Utopic)
The dissect_atn_cpdlc_heur function in asn1/atn-cpdlc/packet-atn-cpdlc-template.c in the ATN-CPDLC dissector in Wireshark 1.12.x before 1.12.4 does not properly follow the TRY/ENDTRY code requirements, which allows remote attackers to cause a denial of service (stack memory corruption and application crash) via a crafted packet.

CVE-2015-2188: (Trusty, Utopic)
epan/dissectors/packet-wcp.c in the WCP dissector in Wireshark 1.10.x before 1.10.13 and 1.12.x before 1.12.4 does not properly initialize a data structure, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted packet that is improperly handled during decompression.

CVE-2015-2189: (Trusty, Utopic)
Off-by-one error in the pcapng_read function in wiretap/pcapng.c in the pcapng file parser in Wireshark 1.10.x before 1.10.13 and 1.12.x before 1.12.4 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via an invalid Interface Statistics Block (ISB) interface ID in a crafted packet.

CVE-2015-2190: (Utopic)
epan/proto.c in Wireshark 1.12.x before 1.12.4 does not properly handle integer data types greater than 32 bits in size, which allows remote attackers to cause a denial of service (assertion failure and application exit) via a crafted packet that is improperly handled by the LLDP dissector.

CVE-2015-2191: (Trusty, Utopic)
Integer overflow in the dissect_tnef function in epan/dissectors/packet-tnef.c in the TNEF dissector in Wireshark 1.10.x before 1.10.13 and 1.12.x before 1.12.4 allows remote attackers to cause a denial of service (infinite loop) via a crafted length field in a packet.

CVE-2015-2192: (Utopic)
Integer overflow in the dissect_osd2_cdb_continuation function in epan/dissectors/packet-scsi-osd.c in the SCSI OSD dissector in Wireshark 1.12.x before 1.12.4 allows remote attackers to cause a denial of service (infinite loop) via a crafted length field in a packet.

------

Vivid is not affected by these CVEs as the archive autosync pulled in a version from Debian that has patches from Wireshark 1.12.4 which fix the problem.

Trusty and Utopic are affected.

Importance set to medium because the majority of these CVEs have a "medium" severity in the Ubuntu CVE tracker.

Marking Fix Released against the devel release as this is already fixed there.

[Thomas Ward (teward)]

Attached is a debdiff for Utopic to address this bug and the 6 CVEs. The included patches were taken from the auto-synced Vivid package, but had their patch names renamed in order to keep the sequential numbering in Utopic, as only security fixes were included, and there is an extra patch in Vivid which would make the CVE patches push the numbering out of sequence.

This bug was fixed in the package wireshark - 1.12.1+g01b65bf-2~ubuntu14.10.3
