Buffer overflow in the MAC-LTE dissector (epan/dissectors/packet-mac-lte.c) in Wireshark 1.2.0 through 1.2.13 and 1.4.0 through 1.4.2 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large number of RARs.

Heap-based buffer overflow in the dissect_ldss_transfer function (epan/dissectors/packet-ldss.c) in the LDSS dissector in Wireshark 1.2.0 through 1.2.12 and 1.4.0 through 1.4.1 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an LDSS packet with a long digest line that triggers memory corruption.

Stack consumption vulnerability in the dissect_ber_unknown function in epan/dissectors/packet-ber.c in the BER dissector in Wireshark 1.4.x before 1.4.1 and 1.2.x before 1.2.12 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a long string in an unknown ASN.1/BER encoded packet, as demonstrated using SNMP.

Untrusted search path vulnerability in Wireshark 0.8.4 through 1.0.15 and 1.2.0 through 1.2.10 allows local users, and possibly remote attackers, to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse airpcap.dll, and possibly other DLLs, that is located in the same folder as a file that automatically launches Wireshark.
