The public API function BIOnewNDEF 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...

CVE-2023-0215

CVE-2023-0215 describes a use-after-free in OpenSSL’s BIO_new_NDEF path used with SMIME/CMS/PKCS7 streaming. When a CMS recipient key is invalid, the filter BIO is freed but the caller’s BIO still holds pointers, allowing use-after-free on BIO_pop(); this can crash the process. Affected internal ...

CVE-2023-0216 Invalid pointer dereference in d2i_PKCS7 functions

An invalid pointer dereference on read can be triggered when an application tries to load malformed PKCS7 data with the d2iPKCS7, d2iPKCS7bio or d2iPKCS7fp functions. The result of the dereference is an application crash which could lead to a denial of service attack. The TLS implementation in...

CVE-2023-0401

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...

CVE-2023-0401

CVE-2023-0401 describes a NULL pointer dereference during PKCS7 data verification in OpenSSL. The digest initialization can fail when the signature hash algorithm is known but the implementation is unavailable, due to a missing check on the initialization return value. This can lead to invalid di...
