Import OpenSSL 3.0.14 (last was 3.0.12)
### Changes between 3.0.13 and 3.0.14 [4 Jun 2024]
* Fixed potential use after free after SSL_free_buffers() is called.
The SSL_free_buffers function is used to free the internal OpenSSL buffer used when processing an incoming record from the network. The call is only expected to succeed if the buffer is not currently in use. However, two scenarios have been identified where the buffer is freed even when still in use.
The first scenario occurs where a record header has been received from the network and processed by OpenSSL, but the full record body has not yet arrived. In this case calling SSL_free_buffers will succeed even though a record has only been partially processed and the buffer is still in use.
The second scenario occurs where a full record containing application data has been received and processed by OpenSSL but the application has only read part of this data. Again a call to SSL_free_buffers will succeed even though the buffer is still in use.
([CVE-2024-4741])
*Matt Caswell*
* Fixed an issue where checking excessively long DSA keys or parameters may be very slow.
Applications that use the functions EVP_PKEY_param_check() or EVP_PKEY_public_check() to check a DSA public key or DSA parameters may experience long delays. Where the key or parameters that are being checked have been obtained from an untrusted source this may lead to a Denial of Service.
To resolve this issue DSA keys larger than OPENSSL_DSA_MAX_MODULUS_BITS will now fail the check immediately with a DSA_R_MODULUS_TOO_LARGE error reason.
([CVE-2024-4603])
*Tom���� Mr��z*
* Fixed an issue where some non-default TLS server configurations can cause unbounded memory growth when processing TLSv1.3 sessions. An attacker may exploit certain server configurations to trigger unbounded memory growth that would lead to a Denial of Service
This problem can occur in TLSv1.3 if the non-default SSL_OP_NO_TICKET option is being used (but not if early_data is also configured and the default anti-replay protection is in use). In this case, under certain conditions, the session cache can get into an incorrect state and it will fail to flush properly as it fills. The session cache will continue to grow in an unbounded manner. A malicious client could deliberately create the scenario for this failure to force a Denial of Service. It may also happen by accident in normal operation.
([CVE-2024-2511])
*Matt Caswell*
* New atexit configuration switch, which controls whether the OPENSSL_cleanup is registered when libcrypto is unloaded. This can be used on platforms where using atexit() from shared libraries causes crashes on exit.
*Randall S. Becker*
### Changes between 3.0.12 and 3.0.13 [30 Jan 2024]
* A file in PKCS12 format can contain certificates and keys and may come from an untrusted source. The PKCS12 specification allows certain fields to be NULL, but OpenSSL did not correctly check for this case. A fix has been applied to prevent a NULL pointer dereference that results in OpenSSL crashing. If an application processes PKCS12 files from an untrusted source using the OpenSSL APIs then that application will be vulnerable to this issue prior to this fix.
OpenSSL APIs that were vulnerable to this are: PKCS12_parse(), PKCS12_unpack_p7data(), PKCS12_unpack_p7encdata(), PKCS12_unpack_authsafes() and PKCS12_newpass().
We have also fixed a similar issue in SMIME_write_PKCS7(). However since this function is related to writing data we do not consider it security significant.
([CVE-2024-0727])
*Matt Caswell*
* When function EVP_PKEY_public_check() is called on RSA public keys, a computation is done to confirm that the RSA modulus, n, is composite. For valid RSA keys, n is a product of two or more large primes and this computation completes quickly. However, if n is an overly large prime, then this computation would take a long time.
An application that calls EVP_PKEY_public_check() and supplies an RSA key obtained from an untrusted source could be vulnerable to a Denial of Service attack.
The function EVP_PKEY_public_check() is not called from other OpenSSL functions however it is called from the OpenSSL pkey command line application. For that reason that application is also vulnerable if used with the "-pubin" and "-check" options on untrusted data.
To resolve this issue RSA keys larger than OPENSSL_RSA_MAX_MODULUS_BITS will now fail the check immediately with an RSA_R_MODULUS_TOO_LARGE error reason.
([CVE-2023-6237])
*Tom���� Mr��z*
* Restore the encoding of SM2 PrivateKeyInfo and SubjectPublicKeyInfo to have the contained AlgorithmIdentifier.algorithm set to id-ecPublicKey rather than SM2.
*Richard Levitte*
* The POLY1305 MAC (message authentication code) implementation in OpenSSL for PowerPC CPUs saves the contents of vector registers in different order than they are restored. Thus the contents of some of these vector registers is corrupted when returning to the caller. The vulnerable code is used only on newer PowerPC processors supporting the PowerISA 2.07 instructions.
The consequences of this kind of internal application state corruption can be various - from no consequences, if the calling application does not depend on the contents of non-volatile XMM registers at all, to the worst consequences, where the attacker could get complete control of the application process. However unless the compiler uses the vector registers for storing pointers, the most likely consequence, if any, would be an incorrect result of some application dependent calculations or a crash leading to a denial of service.
([CVE-2023-6129])
*Rohan McLure*
* Fix excessive time spent in DH check / generation with large Q parameter value.
Applications that use the functions DH_generate_key() to generate an X9.42 DH key may experience long delays. Likewise, applications that use DH_check_pub_key(), DH_check_pub_key_ex() or EVP_PKEY_public_check() to check an X9.42 DH key or X9.42 DH parameters may experience long delays. Where the key or parameters that are being checked have been obtained from an untrusted source this may lead to a Denial of Service.
