[gnutls-devel] GnuTLS | Parsing a certificate containing numerous names or name constraints leads to a DoS attack (#1553)

[Read-only notification of GnuTLS library development activities]

Andreas Metzler commented on a discussion: https://gitlab.com/gnutls/gnutls/-/issues/1553#note_2349709875


This is more involved than the changes for 3.7, due to the gnulib changes [INT_(MULTIPLY|ADD)_OK missing, replaced by coding using _OVERFLOW], ditto for _gnutls_reallocarray. I assume you got these pieces right. Apart from that it looks good to me and the obvious checks, (certtool -i and -e with the cert in this report) show the fix working.
