Blake Bender updated GEODE-6007:
--------------------------------
Summary: Fix LGTM complaints in NC code base (was: Remove use of snprintf
in NC code base)
> Fix LGTM complaints in NC code base
> -----------------------------------
>
> Key: GEODE-6007
> URL: https://issues.apache.org/jira/browse/GEODE-6007
> Project: Geode
> Issue Type: Improvement
> Components: native client
> Reporter: Blake Bender
> Priority: Major
>
> This is bad practice in general, and may open us up to maliciousness. There
> are two main situations in which we find lots of usage of snprintf with raw
> char buffers, which are:
> * formatting messages for exceptions
> * formatting messages for logging
> For the exception messages, we should switch to something known to be safe -
> a vsxprintf implementation, boost::format, std::stringstream, whatever. As
> long as we stop declaring raw char buffers on the stack, it's all good
>
> For logging, the situation is even dumber. The various LOG* macros in the
> code _already_ take a format string and varargs, so as far as I know we
> essentially need to move the printf-style arguments into the logging macro
> and get rid of the other nonsense. We may even buy a tiny performance
> improvement due to the fact that that logging macros can be compiled out of
> the code.
>
> UPDATE: Report from running LGTM on our code may be found at
> [https://lgtm.com/projects/g/apache/geode-native/alerts/?mode=list.] This
> report has issues with tons of printf-style format specifiers, so it catches
> most of the snprintf stuff pointed out above. MANY OF THESE ARE BUFFER
> OVERFLOW ISSUES, and must be addressed in the name of security.
