Integer overflow in perfmonitor preprocessor

Just an output bug. Snort 2.9.7.5 is affected and probably previous versions. In src/preprocessors/spp_perfmonitor.c there is this code: ParseError("Perfmonitor: Invalid argument to \"%s\". The " "value must be an integer between 0 and %d.", PERFMON_ARG__PKT_COUNT, UINT32_MAX) But the printf '%d' is signed and UINT32_MAX is unsigned so you get output like this: Perfmonitor: Invalid argument to "pktcnt". The value must be an integer between 0 and -1. Change '%d' to '%u' to fix. Then you get proper output like: Perfmonitor: Invalid argument to "pktcnt". The value must be an integer between 0 and 4294967295. -Mike Cox
