Thank you for the PR. Is this something that has been fixed in strconv in the intervening time since you opened it? If you find time would you mind merging main? |
…dk.io/math
This fixes potential security issues resulting from extraneous
parsing that used cosmossdk.math.ParseUint which uses math/big.Int
which is a big integer package and can allow uint64 in places
where uint32 is used and there were underflow checks.
The fix for this change was to simply use
strconv.ParseUint(s, 10, BIT_SIZE)
where BIT_SIZE is any of 32 or 64 bits for uint32 and uint64 respectively,
and by extracting the shared code to an internal package.
Fixes PeggyJV#292

Hey @cbrit, I've rebased from the latest on main. Please take a look again.
So the problems weren't in strconv but rather in the usage of it in these libraries, without careful consideration. |
