| CVE-2019-10053 | 1 Suricata-ids | 1 Suricata | 2021-07-21 | 7.5 HIGH | 9.8 CRITICAL |
| 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-2019-18792 | 2 Debian, Suricata-ids | 2 Debian Linux, Suricata | 2021-07-21 | 6.4 MEDIUM | 9.1 CRITICAL |
| An issue was discovered in Suricata 5.0.0. It is possible to bypass/evade any tcp based signature by overlapping a TCP segment with a fake FIN packet. The fake FIN packet is injected just before the PUSH ACK packet we want to bypass. The PUSH ACK packet (containing the data) will be ignored by Suricata because it overlaps the FIN packet (the sequence and ack number are identical in the two packets). The client will ignore the fake FIN packet because the ACK flag is not set. Both linux and windows clients are ignoring the injected packet. | |||||
| CVE-2019-16410 | 1 Suricata-ids | 1 Suricata | 2019-10-18 | 6.4 MEDIUM | 9.1 CRITICAL |
| 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-2019-16411 | 1 Suricata-ids | 1 Suricata | 2019-10-02 | 7.5 HIGH | 9.8 CRITICAL |
| 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 data). Then, "flag = *(o->data + 3)" places one beyond the 3 bytes, because the code should have been "flag = *(o->data + 1)" instead. | |||||
| CVE-2019-15699 | 1 Suricata-ids | 1 Suricata | 2019-09-25 | 6.4 MEDIUM | 9.1 CRITICAL |
| 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 the HSHelloExtensions part of the packet. | |||||
| CVE-2018-10244 | 1 Suricata-ids | 1 Suricata | 2019-04-07 | 7.5 HIGH | 9.8 CRITICAL |
| Suricata version 4.0.4 incorrectly handles the parsing of an EtherNet/IP PDU. A malformed PDU can cause the parsing code to read beyond the allocated data because DecodeENIPPDU in app-layer-enip-commmon.c has an integer overflow during a length check. | |||||
