Description

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.

Weakness classification

CWE-125: Out-of-bounds Read
CWE-191: Integer Underflow (Wrap or Wraparound)
