Branch: pkgsrc-2022Q4, Version: 1.1.1t, Package name: openssl-1.1.1t, Maintainer: pkgsrc-users

The OpenSSL Project is a collaborative effort to develop a
robust, commercial-grade, full-featured, and Open Source
toolkit implementing the Secure Sockets Layer (SSL v2/v3)
and Transport Layer Security (TLS v1) protocols as well as
a full-strength general purpose cryptography library. The
project is managed by a worldwide community of volunteers
that use the Internet to communicate, plan, and develop the
OpenSSL toolkit and its related documentation.

   openssl: Update to 1.1.1t.

   Changes between 1.1.1s and 1.1.1t [7 Feb 2023]

    *) Fixed X.400 address type confusion in X.509 GeneralName.

      There is a type confusion vulnerability relating to X.400 address processing
      inside an X.509 GeneralName. X.400 addresses were parsed as an ASN1_STRING
      but subsequently interpreted by GENERAL_NAME_cmp as an ASN1_TYPE. This
      vulnerability may allow an attacker who can provide a certificate chain and
      CRL (neither of which need have a valid signature) to pass arbitrary
      pointers to a memcmp call, creating a possible read primitive, subject to
      some constraints. Refer to the advisory for more information. Thanks to
      David Benjamin for discovering this issue. (CVE-2023-0286)

      This issue has been fixed by changing the public header file definition of
      GENERAL_NAME so that x400Address reflects the implementation. It was not
      possible for any existing application to successfully use the existing
      definition; however, if any application references the x400Address field
      (e.g. in dead code), note that the type of this field has changed. There is
      no ABI change.

    *) Fixed Use-after-free following BIO_new_NDEF.

      The public API function BIO_new_NDEF is a helper function used for
      streaming ASN.1 data via a BIO. It is primarily used internally to OpenSSL
      to support the SMIME, CMS and PKCS7 streaming capabilities, but may also
      be called directly by end user applications.

      The function receives a BIO from the caller, prepends a new BIO_f_asn1
      filter BIO onto the front of it to form a BIO chain, and then returns
      the new head of the BIO chain to the caller. Under certain conditions,
      for example if a CMS recipient public key is invalid, the new filter BIO
      is freed and the function returns a NULL result indicating a failure.
      However, in this case, the BIO chain is not properly cleaned up and the
      BIO passed by the caller still retains internal pointers to the previously
      freed filter BIO. If the caller then goes on to call BIO_pop() on the BIO
      then a use-after-free will occur. This will most likely result in a crash.
      (CVE-2023-0215)

    *) Fixed Double free after calling PEM_read_bio_ex.

      The function PEM_read_bio_ex() reads a PEM file from a BIO and parses and
      decodes the "name" (e.g. "CERTIFICATE"), any header \ 
data and the payload
      data. If the function succeeds then the "name_out", \ 
"header" and "data"
      arguments are populated with pointers to buffers containing the relevant
      decoded data. The caller is responsible for freeing those buffers. It is
      possible to construct a PEM file that results in 0 bytes of payload data.
      In this case PEM_read_bio_ex() will return a failure code but will populate
      the header argument with a pointer to a buffer that has already been freed.
      If the caller also frees this buffer then a double free will occur. This
      will most likely lead to a crash.

      The functions PEM_read_bio() and PEM_read() are simple wrappers around
      PEM_read_bio_ex() and therefore these functions are also directly affected.

      These functions are also called indirectly by a number of other OpenSSL
      functions including PEM_X509_INFO_read_bio_ex() and
      SSL_CTX_use_serverinfo_file() which are also vulnerable. Some OpenSSL
      internal uses of these functions are not vulnerable because the caller does
      not free the header argument if PEM_read_bio_ex() returns a failure code.
      (CVE-2022-4450)
      [Kurt Roeckx, Matt Caswell]

    *) Fixed Timing Oracle in RSA Decryption.

      A timing based side channel exists in the OpenSSL RSA Decryption
      implementation which could be sufficient to recover a plaintext across
      a network in a Bleichenbacher style attack. To achieve a successful
      decryption an attacker would have to be able to send a very large number
      of trial messages for decryption. The vulnerability affects all RSA padding
      modes: PKCS#1 v1.5, RSA-OEAP and RSASVE.
      (CVE-2022-4304)
