CVE-2022-4450

The function PEMreadbioex 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 "nameout", "header" and "data" arguments are populated with pointers to buffers containing the relevant decoded data...

CVE-2022-4450 Double free after calling PEM_read_bio_ex

The function PEMreadbioex reads a PEM file from a BIO and parses and decodes the "name" e.g. "CERTIFICATE", any header data and the payload data.

CVE-2023-0215

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 Use-after-free following BIO_new_NDEF

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-2023-0217 NULL dereference validating DSA public key

An invalid pointer dereference on read can be triggered when an application tries to check a malformed DSA public key by the EVPPKEYpubliccheck function. This will most likely lead to an application crash. This function can be called on public keys supplied from untrusted sources which could allo...

CVE-2023-0217

CVE-2023-0217 is an OpenSSL vulnerability: an invalid pointer dereference on read when validating a malformed DSA public key via EVP_PKEY_public_check(), likely crashing the application and enabling denial of service. Affected context in connected documents confirms OpenSSL-related advisories and...

CVE-2023-0286 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 ASN1STRING but the public structure definition for GENERALNAME incorrectly specified the type of the x400Address field as ASN1TYPE. This field is subsequentl...

CVE-2023-0286

CVE-2023-0286 is a type-confusion bug in OpenSSL related to X.400 address processing inside X.509 GeneralName. The public GENERAL_NAME.x400Address was defined as ASN1_TYPE instead of ASN1_STRING, causing GeneralName_cmp to treat it as a pointer, which under CRL_CHECK can allow an attacker to pass...
