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.
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.
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.
Due to a failure in validating the length provided by an attacker-crafted CP2179 packet, Wireshark versions 2.0.0 through 4.0.7 is susceptible to a divide by zero allowing for a denial of service attack.
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 2.4.0 to 2.4.1, 2.2.0 to 2.2.9, and 2.0.0 to 2.0.15, the DMP dissector could crash. This was addressed in epan/dissectors/packet-dmp.c by validating a string length.
