The Lucent/Ascend file parser in Wireshark 1.2.x before 1.2.18, 1.4.x through 1.4.7, and 1.6.0 allows remote attackers to cause a denial of service (infinite loop) via malformed packets.
The dissect_dcm_main function in epan/dissectors/packet-dcm.c in the DICOM dissector in Wireshark 1.2.x before 1.2.17 and 1.4.x before 1.4.7 allows remote attackers to cause a denial of service (infinite loop) via an invalid PDU length.
Wireshark 1.2.x before 1.2.17 and 1.4.x before 1.4.7 allows user-assisted remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted Diameter dictionary file.
The snoop_read function in wiretap/snoop.c in Wireshark 1.2.x before 1.2.17 and 1.4.x before 1.4.7 does not properly handle certain virtualizable buffers, which allows remote attackers to cause a denial of service (application crash) via a large length value in a snoop file that triggers a stack-based buffer over-read.
Double free vulnerability in the tvb_uncompress function in epan/tvbuff.c in Wireshark 1.2.x before 1.2.17 and 1.4.x before 1.4.7 allows remote attackers to cause a denial of service (application crash) via a packet with malformed data that uses zlib compression.
Integer underflow in the visual_read function in wiretap/visual.c in Wireshark 1.2.x before 1.2.17 and 1.4.x before 1.4.7 allows remote attackers to cause a denial of service (application crash) via a malformed Visual Networks file that triggers a heap-based buffer over-read.
epan/dissectors/packet-ntlmssp.c in the NTLMSSP dissector in Wireshark before 1.4.4 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted .pcap file.
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.
Stack-based buffer overflow in the ASN.1 BER dissector in Wireshark 0.10.13 through 1.0.14 and 1.2.0 through 1.2.9 has unknown impact and remote attack vectors. NOTE: this issue exists because of a CVE-2010-2284 regression.
