patch 9.0.2110: [security]: overflow in ex address parsing Commit: https://github.com/vim/vim/commit/060623e4a3bc72b011e7cd92bedb3bfb64e06200 Author: Christian Brabandt <cb@256bit.org> Date: Tue Nov 14 21:33:29 2023 +0100 patch 9.0.2110: [security]: overflow in ex address parsing Problem: [security]: overflow in ex address parsing Solution: Verify that lnum is positive, before substracting from LONG_MAX [security]: overflow in ex address parsing When parsing relative ex addresses one may unintentionally cause an overflow (because LONG_MAX - lnum will overflow for negative addresses). So verify that lnum is actually positive before doing the overflow check. Signed-off-by: Christian Brabandt <cb@256bit.org>
