A Buffer Overflow in Wireshark before 4.2.0 allows a remote attacker to cause a denial of service via the wsutil/to_str.c, and format_fractional_part_nsecs components. NOTE: this is disputed by the vendor because neither release 4.2.0 nor any other release was affected.

A buffer overflow in Wireshark before 4.2.0 allows a remote attacker to cause a denial of service via the pan/addr_resolv.c, and ws_manuf_lookup_str(), size components. NOTE: this is disputed by the vendor because neither release 4.2.0 nor any other release was affected.

An issue in Wireshark before 4.2.0 allows a remote attacker to cause a denial of service via the packet-bgp.c, dissect_bgp_open(tvbuff_t*tvb, proto_tree*tree, packet_info*pinfo), optlen components. NOTE: this is disputed by the vendor because neither release 4.2.0 nor any other release was affected.

In Wireshark through 3.2.7, the Facebook Zero Protocol (aka FBZERO) dissector could enter an infinite loop. This was addressed in epan/dissectors/packet-fbzero.c by correcting the implementation of offset advancement.

In Wireshark through 2.6.2, the create_app_running_mutex function in wsutil/file_util.c calls SetSecurityDescriptorDacl to set a NULL DACL, which allows attackers to modify the access control arbitrarily.

The netmonrec_comment_destroy function in wiretap/netmon.c in Wireshark through 2.4.4 performs a free operation on an uninitialized memory address, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.

In Wireshark before 2.2.12, the MRDISC dissector misuses a NULL pointer and crashes. This was addressed in epan/dissectors/packet-mrdisc.c by validating an IPv4 address. This vulnerability is similar to CVE-2017-9343.

The File_read_line function in epan/wslua/wslua_file.c in Wireshark through 2.2.11 does not properly strip '\n' characters, which allows remote attackers to cause a denial of service (buffer underflow and application crash) via a crafted packet that triggers the attempted processing of an empty line.

In Wireshark 2.2.4 and earlier, a crafted or malformed STANAG 4607 capture file will cause an infinite loop and memory exhaustion. If the packet size field in a packet header is null, the offset to read from will not advance, causing continuous attempts to read the same zero length packet. This will quickly exhaust all system memory.

Heap-based buffer overflow in wiretap/pcapng.c in Wireshark before 1.2 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted capture file.

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.

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.

Integer overflow in wiretap/erf.c in Wireshark before 1.2.2 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted erf file, related to an "unsigned integer wrap vulnerability."

Unspecified vulnerability in Wireshark before 1.0.7 has unknown impact and attack vectors.

Format string vulnerability in the PROFINET/DCP (PN-DCP) dissector in Wireshark 1.0.6 and earlier allows remote attackers to execute arbitrary code via a PN-DCP packet with format string specifiers in the station name. NOTE: some of these details are obtained from third party information.

Wireshark 1.0.4 and earlier allows remote attackers to cause a denial of service via a long SMTP request, which triggers an infinite loop.

Wireshark (formerly Ethereal) 0.9.7 through 1.0.2 allows attackers to cause a denial of service (hang) via a crafted NCP packet that triggers an infinite loop.

Wireshark 0.99.5 and 0.10.x up to 0.10.14, when running on certain systems, allows remote attackers to cause a denial of service (crash) via crafted iSeries capture files that trigger a SIGTRAP.

Wireshark before 0.99.6 allows remote attackers to cause a denial of service via malformed (1) SSL or (2) MMS packets that trigger an infinite loop.

Off-by-one error in the DHCP/BOOTP dissector in Wireshark before 0.99.6 allows remote attackers to cause a denial of service (crash) via crafted DHCP-over-DOCSIS packets.
