CVE-2023-0401

Status Candidate

Overview

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. 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.

OpenSSL is a robust, fully featured Open Source toolkit implementing the Secure Sockets Layer and Transport Layer Security protocols with full-strength cryptography world-wide. The 3.x series is the current major version of OpenSSL.

Changes: Fixed NULL dereference during PKCS7 data verification. Fixed X.400 address type confusion in X.509 GeneralName. Fixed NULL dereference validating DSA public key. Fixed invalid pointer dereference in d2i_PKCS7 functions. Fixed use-after-free following BIO_new_NDEF. Fixed double-free after calling PEM_read_bio_ex. Fixed timing oracle in RSA decryption. Fixed X.509 Name Constraints read buffer overflow. Fixed X.509 policy constraints double locking.

Ubuntu Security Notice 5844-1 - David Benjamin discovered that OpenSSL incorrectly handled X.400 address processing. A remote attacker could possibly use this issue to read arbitrary memory contents or cause OpenSSL to crash, resulting in a denial of service. Corey Bonnell discovered that OpenSSL incorrectly handled X.509 certificate verification. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service. This issue only affected Ubuntu 22.04 LTS and Ubuntu 22.10.
