Subject: Fix bug #79589: ssl3_read_n:unexpected eof while reading
|
|
|
|
The unexpected EOF failure was introduced in OpenSSL 3.0 to prevent
|
|
truncation attack. However there are many non complaint servers and
|
|
it is causing break for many users including potential majority
|
|
of those where the truncation attack is not applicable. For that reason
|
|
we try to keep behavior consitent with older OpenSSL versions which is
|
|
also the path chosen by some other languages and web servers.
|
|
|
|
Closes GH-8369
