An integer overflow in the RFC3164 parser in One Identity syslog-ng 3.0 through 3.37 allows remote attackers to cause a Denial of Service via crafted syslog input that is mishandled by the tcp or network function. syslog-ng Premium Edition 7.0.30 and syslog-ng Store Box 6.10.0 are also affected.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
