    CVE-2019-10053

    Published: 13 May 2019Last Modified: 8 Jul 2026

    Summary:

    Details: 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.
