Affected: AlmaLinux:9: openssl, AlmaLinux:9: openssl-devel, AlmaLinux:9: openssl-libs, AlmaLinux:9: openssl-perl

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library.

Security Fix(es):

* openssl: read buffer overflow in X.509 certificate verification (CVE-2022-4203) * openssl: timing attack in RSA Decryption implementation (CVE-2022-4304) * openssl: double free after calling PEM_read_bio_ex (CVE-2022-4450) * openssl: use-after-free following BIO_new_NDEF (CVE-2023-0215) * openssl: invalid pointer dereference in d2i_PKCS7 functions (CVE-2023-0216) * openssl: NULL dereference validating DSA public key (CVE-2023-0217) * openssl: X.400 address type confusion in X.509 GeneralName (CVE-2023-0286) * openssl: NULL dereference during PKCS7 data verification (CVE-2023-0401)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

* HMAC generation should reject key lengths < 112 bits or provide an indicator in FIPS mode (BZ#2144000) * In FIPS mode, openssl should set a minimum length for passwords in PBKDF2 (BZ#2144003) * stunnel consumes high amount of memory when pestered with TCP connections without a TLS handshake (BZ#2144008) * In FIPS mode, openssl should reject SHAKE as digest for RSA-OAEP or provide an indicator (BZ#2144010) * In FIPS mode, openssl should reject RSASSA-PSS salt lengths larger than the output size of t…

fkie_cve-2023-0401

The unavailability of an algorithm can be caused by using FIPS enabled configuration of providers or more commonly by not loading the legacy provider.

PKCS7 data is processed by the SMIME library calls and also by the time stamp (TS) library calls. The TLS implementation in OpenSSL does not call these functions however third party applications would be affected if they call these functions to verify signatures on untrusted data.

GHSA-vrh7-x64v-7vxq — openssl-src contains `NULL` dereference during PKCS7 data verification

Affected: crates.io: openssl-src

A `NULL` pointer can be dereferenced when signatures are being verified on PKCS7 `signed` or `signedAndEnveloped` data. In case the hash algorithm used for the signature is known to the OpenSSL library but the implementation of the hash algorithm is not available the digest initialization will fail. There is a missing check for the return value from the initialization function which later leads to invalid usage of the digest API most likely leading to a crash. The unavailability of an algorithm can be caused by using FIPS enabled configuration of providers or more commonly by not loading the legacy provider.

OESA-2023-1135 — edk2 security update

Affected: openEuler:20.03-LTS-SP1: edk2, openEuler:20.03-LTS-SP3: edk2, openEuler:22.03-LTS: edk2, openEuler:22.03-LTS-SP1: edk2

EDK II is a modern, feature-rich, cross-platform firmware development environment for the UEFI and PI specifications. Security Fix(es): 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. This scenario occurs directly in the internal function B64_write_ASN1() which may cause BIO_new_NDEF() to be called and will subsequently call BIO_pop() on the BIO. This internal function is in turn called by the public API functions PEM_write_bio_ASN1_stream, PEM_write_bio_CMS_stream, PEM_write_bio_PKCS7_stream, SMIME_write_ASN1, SMIME_write_CMS and SMIME_write_PKCS7. Other public API functions that may be impacted by this include i2d_ASN1_…
