Overview

Affected versions of this package are vulnerable to Integer Overflow or Wraparound due to an integer overflow in the __vsyslog_internal function. An attacker can cause undefined behavior by calling syslog or vsyslog with an excessively long message, which leads to miscalculation of the buffer size needed to store the message.
