Description

The libcurl API function called `curl_maprintf()` before version 7.51.0 can be tricked into doing a double-free due to an unsafe `size_t` multiplication, on systems using 32 bit `size_t` variables.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

v < 7.51.07.51.0
Affected range stops below 7.51.0, so it looks safe — our inference, not a vendor statement
