It is recommended that administrators running suricata check for an updated version of the software for their operating system. - --------------------------BEGIN INCLUDED TEXT-------------------- suricata -- buffer over-read Affected packages suricata < 4.1.4 Details VuXML ID 3b903bf3-7f94-11e9-8a5f-c85b76ce9b5a Discovery 2019-03-15 Entry 2019-05-26 Modified 2019-05-26 Mitre reports: 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.
