dequis 632b0ce5e6 Add parse_uint function to improve integer overflow handling ... Originally found by oss-fuzz (issue 525) in get_ansi_color using ubsan. After a lot of analysis I'm 99% sure this isn't security relevant so it's fine to handle this publicly. The fix is mainly adding a function that does it right and use it everywhere. This is harder than it seems because the strtol() family of functions doesn't have the friendliest of interfaces. Aside from get_ansi_color(), there were other pieces of code that used the same (out*10+(*in-'0')) pattern, like the parse_size() and parse_time_interval() functions, which are mostly used for settings. Those are interesting cases, since they multiply the parsed number (resulting in more overflows) and they write to a signed integer parameter (which can accidentally make the uints negative without UB) Thanks to Pascal Cuoq for enlightening me about the undefined behavior of parse_size (and, in particular, the implementation-defined behavior of one of the WIP versions of this commit, where something like signed integer overflow happened, but it was legal). Also for writing tis-interpreter, which is better than ubsan to verify these things.		2017-05-18 00:21:11 -03:00
