MEDIUM 5.3: In OISF LibHTP before 0.5.31, as used in Suricata 4.1.4 and other products, an HTTP protocol parsing error causes the http_header signature to not alert on a response with a single \r\n ending.

CVE-2019-16411: An issue was discovered in Suricata 4.1.4

Wed, 17 Jun 2026 02:22:15 +0000

CRITICAL 9.8: An issue was discovered in Suricata 4.1.4. By sending multiple IPv4 packets that have invalid IPv4Options, the function IPV4OptValidateTimestamp in decode-ipv4.c tries to access a memory region that is not allocated. There is a check for o->len < 5 (corresponding to 2 bytes of header and 3 bytes of

CVE-2019-16410: An issue was discovered in Suricata 4.1.4

Wed, 17 Jun 2026 02:22:15 +0000

CRITICAL 9.1: An issue was discovered in Suricata 4.1.4. By sending multiple fragmented IPv4 packets, the function Defrag4Reassemble in defrag.c tries to access a memory region that is not allocated, because of a lack of header_len checking.

CVE-2019-15699: An issue was discovered in app-layer-ssl.c in Suricata 4.1.4

Wed, 17 Jun 2026 02:20:53 +0000

CRITICAL 9.1: An issue was discovered in app-layer-ssl.c in Suricata 4.1.4. Upon receiving a corrupted SSLv3 (TLS 1.2) packet, the parser function TLSDecodeHSHelloExtensions tries to access a memory region that is not allocated, because the expected length of HSHelloExtensions does not match the real length of th

CVE-2019-10056: An issue was discovered in Suricata 4.1.3

Wed, 17 Jun 2026 02:10:07 +0000

HIGH 7.5: An issue was discovered in Suricata 4.1.3. The code mishandles the case of sending a network packet with the right type, such that the function DecodeEthernet in decode-ethernet.c is executed a second time. At this point, the algorithm cuts the first part of the packet and doesn't determine the curr

CVE-2019-10055: An issue was discovered in Suricata 4.1.3

Wed, 17 Jun 2026 02:10:07 +0000

HIGH 7.5: An issue was discovered in Suricata 4.1.3. The function ftp_pasv_response lacks a check for the length of part1 and part2, leading to a crash within the ftp/mod.rs file.

CVE-2019-10054: An issue was discovered in Suricata 4.1.3

Wed, 17 Jun 2026 02:10:06 +0000

HIGH 7.5: An issue was discovered in Suricata 4.1.3. The function process_reply_record_v3 lacks a check for the length of reply.data. It causes an invalid memory access and the program crashes within the nfs/nfs3.rs file.

CVE-2019-10052: An issue was discovered in Suricata 4.1.3

Wed, 17 Jun 2026 02:10:06 +0000

HIGH 7.5: An issue was discovered in Suricata 4.1.3. If the network packet does not have the right length, the parser tries to access a part of a DHCP packet. At this point, the Rust environment runs into a panic in parse_clientid_option in the dhcp/parser.rs file.

CVE-2019-10051: An issue was discovered in Suricata 4.1.3

Wed, 17 Jun 2026 02:10:06 +0000

HIGH 7.5: An issue was discovered in Suricata 4.1.3. If the function filetracker_newchunk encounters an unsafe "Some(sfcm) => { ft.new_chunk }" item, then the program enters an smb/files.rs error condition and crashes.

CVE-2019-10053: An issue was discovered in Suricata 4.1.x before 4.1.4

Wed, 17 Jun 2026 02:10:06 +0000

CRITICAL 9.8: An issue was discovered in Suricata 4.1.x before 4.1.4. If the input of the function SSHParseBanner is composed only of a \n character, then the program runs into a heap-based buffer over-read. This occurs because the erroneous search for \r results in an integer underflow.

CVE-2018-18956: The ProcessMimeEntity function in util-decode-mime.c in Suricata 4.x before 4.0.6 allows remote attackers to c

Wed, 17 Jun 2026 01:48:11 +0000

HIGH 7.5: The ProcessMimeEntity function in util-decode-mime.c in Suricata 4.x before 4.0.6 allows remote attackers to cause a denial of service (segfault and daemon crash) via crafted input to the SMTP parser, as exploited in the wild in November 2018.

CVE-2018-14568: Suricata before 4.0.5 stops TCP stream inspection upon a TCP RST from a server

Wed, 17 Jun 2026 01:41:12 +0000

HIGH 7.5: Suricata before 4.0.5 stops TCP stream inspection upon a TCP RST from a server. This allows detection bypass because Windows TCP clients proceed with normal processing of TCP data that arrives shortly after an RST (i.e., they act as if the RST had not yet been received).

CVE-2016-10728: An issue was discovered in Suricata before 3.1.2

Wed, 17 Jun 2026 00:40:14 +0000

MEDIUM 5.3: An issue was discovered in Suricata before 3.1.2. If an ICMPv4 error packet is received as the first packet on a flow in the to_client direction, it confuses the rule grouping lookup logic. The toclient inspection will then continue with the wrong rule group. This can lead to missed detection.

CVE-2018-6794: Suricata before 4.0.4 is prone to an HTTP detection bypass vulnerability in detect.c and stream-tcp.c

Wed, 17 Jun 2026 02:02:17 +0000

MEDIUM 5.3: Suricata before 4.0.4 is prone to an HTTP detection bypass vulnerability in detect.c and stream-tcp.c. If a malicious server breaks a normal TCP flow and sends data before the 3-way handshake is complete, then the data sent by the malicious server will be accepted by web clients such as a web browse
