Description Robert Frohl 2019-05-14 09:12:40 UTC

CVE-2019-10053

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.
