[gnutls-devel] GnuTLS | Fix out-of-bounds memcpy in gnutls_realloc_zero() (!1592)

[Read-only notification of GnuTLS library development activities]

Tobias Heider commented on a discussion: https://gitlab.com/gnutls/gnutls/-/merge_requests/1592#note_951086001

Right, as long as it never goes down to <= 1 or frees it explicitly gets freed. Tracking the original allocation size to make the logic more robust is not really possible with this API (and probably not worth it either).

In the end it is a time vs space tradeoff. I am fine with going for memory efficiency.
