OpenSSL 1.1.1i ist seit dem 08. Dezember 2020 verfügbar
Changes between 1.1.1h and 1.1.1i [8 Dec 2020]
*) Fixed NULL pointer deref in the GENERAL_NAME_cmp function
This function could crash if both GENERAL_NAMEs contain an EDIPARTYNAME.
If an attacker can control both items being compared then this could lead
to a possible denial of service attack. OpenSSL itself uses the
GENERAL_NAME_cmp function for two purposes:
1) Comparing CRL distribution point names between an available CRL and a
CRL distribution point embedded in an X509 certificate
2) When verifying that a timestamp response token signer matches the
timestamp authority name (exposed via the API functions
TS_RESP_verify_response and TS_RESP_verify_token)
(CVE-2020-1971)
[Matt Caswell]
*) Add support for Apple Silicon M1 Macs with the darwin64-arm64-cc target.
[Stuart Carnie]
*) The security callback, which can be customised by application code, supports
the security operation SSL_SECOP_TMP_DH. This is defined to take an EVP_PKEY
in the "other" parameter. In most places this is what is passed. All these
places occur server side. However there was one client side call of this
security operation and it passed a DH object instead. This is incorrect
according to the definition of SSL_SECOP_TMP_DH, and is inconsistent with all
of the other locations. Therefore this client side call has been changed to
pass an EVP_PKEY instead.
[Matt Caswell]
*) In 1.1.1h, an expired trusted (root) certificate was not anymore rejected
when validating a certificate path. This check is restored in 1.1.1i.
