CVE-2019-17420 2 Oisf, Suricata-ids 2 Libhtp, Suricata 2019-10-16 5.0
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-2018-14568 1 Suricata-ids 1 Suricata 2019-10-03 5.0
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...
CVE-2019-16411 1 Suricata-ids 1 Suricata 2019-10-02 7.5
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 <...
CVE-2019-15699 1 Suricata-ids 1 Suricata 2019-09-25 6.4
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...
CVE-2019-16410 1 Suricata-ids 1 Suricata 2019-09-25 6.4
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-2019-10056 1 Suricata-ids 1 Suricata 2019-09-05 5.0
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...
CVE-2019-10051 1 Suricata-ids 1 Suricata 2019-09-05 5.0
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-2019-10055 1 Suricata-ids 1 Suricata 2019-09-05 7.8
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-2019-10052 1 Suricata-ids 1 Suricata 2019-09-04 5.0
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-2019-10054 1 Suricata-ids 1 Suricata 2019-09-04 5.0
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-2019-10053 1 Suricata-ids 1 Suricata 2019-05-14 7.5
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...
CVE-2019-10050 1 Suricata-ids 1 Suricata 2019-05-14 5.0
A buffer over-read issue was discovered in Suricata 4.1.x before 4.1.4. If the input of the decode-mpls.c function DecodeMPLS is composed only of a packet of source address and destination address plus the correct type field and the right number...
CVE-2018-10242 2 Suricata-ids, Debian 2 Suricata, Debian Linux 2019-05-06 5.0
Suricata version 4.0.4 incorrectly handles the parsing of the SSH banner. A malformed SSH banner can cause the parsing code to read beyond the allocated data because SSHParseBanner in app-layer-ssh.c lacks a length check.
CVE-2018-6794 2 Suricata-ids, Debian 2 Suricata, Debian Linux 2019-03-01 5.0
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...
CVE-2018-18956 1 Suricata-ids 1 Suricata 2019-01-30 5.0
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-2013-5919 2 Openinfosecfoundation, Suricata-ids 2 Suricata, Suricata 2018-10-30 5.0
Suricata before 1.4.6 allows remote attackers to cause a denial of service (crash) via a malformed SSL record.
CVE-2016-10728 1 Suricata-ids 1 Suricata 2018-09-20 5.0
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...
