Changes between 1.1.1l and 1.1.1m [14 Dec 2021]

*) Avoid loading of a dynamic engine twice.
[Bernd Edlinger]

*) Fixed building on Debian with kfreebsd kernels
[Mattias Ellert]

*) Prioritise DANE TLSA issuer certs over peer certs
[Viktor Dukhovni]

*) Fixed random API for MacOS prior to 10.12
These MacOS versions don't support the CommonCrypto APIs
[Lenny Primak]

Changes between 1.1.1k and 1.1.1l [24 Aug 2021]

*) Fixed an SM2 Decryption Buffer Overflow.

In order to decrypt SM2 encrypted data an application is expected
to call the API function EVP_PKEY_decrypt(). Typically an application
will call this function twice. The first time, on entry, the "out"
parameter can be NULL and, on exit, the "outlen" parameter is
populated with the buffer size required to hold the decrypted
plaintext. The application can then allocate a sufficiently sized
buffer and call EVP_PKEY_decrypt() again, but this time passing
a non-NULL value for the "out" parameter.

A bug in the implementation of the SM2 decryption code means that
the calculation of the buffer size required to hold the plaintext
returned by the first call to EVP_PKEY_decrypt() can be smaller
than the actual size required by the second call. This can lead to
a buffer overflow when EVP_PKEY_decrypt() is called by the application
a second time with a buffer that is too small.

A malicious attacker who is able present SM2 content for decryption
to an application could cause attacker chosen data to overflow the
buffer by up to a maximum of 62 bytes altering the contents of
other data held after the buffer, possibly changing application
behaviour or causing the application to crash. The location of the
buffer is application dependent but is typically heap allocated.
(CVE-2021-3711)
[Matt Caswell]

*) Fixed various read buffer overruns processing ASN.1 strings

ASN.1 strings are represented internally within OpenSSL as an
ASN1_STRING structure which contains a buffer holding the string
data and a field holding the buffer length. This contrasts with
normal C strings which are repesented as a buffer for the string
data which is terminated with a NUL (0) byte.

Although not a strict requirement, ASN.1 strings that are parsed
using OpenSSL's own "d2i" functions (and other similar parsing
functions) as well as any string whose value has been set with the
ASN1_STRING_set() function will additionally NUL terminate the byte
array in the ASN1_STRING structure.

However, it is possible for applications to directly construct
valid ASN1_STRING structures which do not NUL terminate the byte
array by directly setting the "data" and "length" fields in the
ASN1_STRING array. This can also happen by using the ASN1_STRING_set0()
function.

Numerous OpenSSL functions that print ASN.1 data have been found
to assume that the ASN1_STRING byte array will be NUL terminated,
even though this is not guaranteed for strings that have been
directly constructed. Where an application requests an ASN.1
structure to be printed, and where that ASN.1 structure contains
ASN1_STRINGs that have been directly constructed by the application
without NUL terminating the "data" field, then a read buffer overrun
can occur.

The same thing can also occur during name constraints processing
of certificates (for example if a certificate has been directly
constructed by the application instead of loading it via the OpenSSL
parsing functions, and the certificate contains non NUL terminated
ASN1_STRING structures). It can also occur in the X509_get1_email(),
X509_REQ_get1_email() and X509_get1_ocsp() functions.

If a malicious actor can cause an application to directly construct
an ASN1_STRING and then process it through one of the affected
OpenSSL functions then this issue could be hit. This might result
in a crash (causing a Denial of Service attack). It could also
result in the disclosure of private memory contents (such as private
keys, or sensitive plaintext).

Changes between 1.1.1d and 1.1.1e [17 Mar 2020]
*) Properly detect EOF while reading in libssl. Previously if we hit an EOF
while reading in libssl then we would report an error back to the
application (SSL_ERROR_SYSCALL) but errno would be 0. We now add
an error to the stack (which means we instead return SSL_ERROR_SSL) and
therefore give a hint as to what went wrong.
[Matt Caswell]

*) Check that ed25519 and ed448 are allowed by the security level. Previously
signature algorithms not using an MD were not being checked that they were
allowed by the security level.
[Kurt Roeckx]

*) Fixed SSL_get_servername() behaviour. The behaviour of SSL_get_servername()
was not quite right. The behaviour was not consistent between resumption
and normal handshakes, and also not quite consistent with historical
behaviour. The behaviour in various scenarios has been clarified and
it has been updated to make it match historical behaviour as closely as
possible.
[Matt Caswell]

*) [VMS only] The header files that the VMS compilers include automatically,
__DECC_INCLUDE_PROLOGUE.H and __DECC_INCLUDE_EPILOGUE.H, use pragmas that
the C++ compiler doesn't understand. This is a shortcoming in the
compiler, but can be worked around with __cplusplus guards.

C++ applications that use OpenSSL libraries must be compiled using the
qualifier '/NAMES=(AS_IS,SHORTENED)' to be able to use all the OpenSSL
functions. Otherwise, only functions with symbols of less than 31
characters can be used, as the linker will not be able to successfully
resolve symbols with longer names.
[Richard Levitte]

*) Corrected the documentation of the return values from the EVP_DigestSign*
set of functions. The documentation mentioned negative values for some
errors, but this was never the case, so the mention of negative values
was removed.

Code that followed the documentation and thereby check with something
like 'EVP_DigestSignInit(...) <= 0' will continue to work undisturbed.
[Richard Levitte]

*) Fixed an an overflow bug in the x64_64 Montgomery squaring procedure
used in exponentiation with 512-bit moduli. No EC algorithms are
affected. Analysis suggests that attacks against 2-prime RSA1024,
3-prime RSA1536, and DSA1024 as a result of this defect would be very
difficult to perform and are not believed likely. Attacks against DH512
are considered just feasible. However, for an attack the target would
have to re-use the DH512 private key, which is not recommended anyway.
Also applications directly using the low level API BN_mod_exp may be
affected if they use BN_FLG_CONSTTIME.
(CVE-2019-1551)
[Andy Polyakov]

*) Added a new method to gather entropy on VMS, based on SYS$GET_ENTROPY.
The presence of this system service is determined at run-time.
[Richard Levitte]

*) Added newline escaping functionality to a filename when using openssl dgst.
This output format is to replicate the output format found in the '*sum'
checksum programs. This aims to preserve backward compatibility.
[Matt Eaton, Richard Levitte, and Paul Dale]

*) Print all values for a PKCS#12 attribute with 'openssl pkcs12', not just
the first value.
