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)

Multiple security vulnerabilities affect the openssl package. Issue summary: PBMAC1 parameters in PKCS#12 files are missing validation which can trigger a stack-based buffer overflow, invalid pointer or NULL pointer dereference during MAC verification. See references for individual vulnerability details.

A read buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer.

The read buffer overrun might result in a crash which could lead to a denial of service attack. In theory it could also result in the disclosure of private memory contents (such as private keys, or sensitive plaintext) although we are not aware of any working exploit leading to memory contents disclosure as of the time of release of this advisory.

In a TLS client, this can be triggered by connecting to a malicious server. In a TLS server, this can be triggered if the server requests client authentication and a malicious client connects.

A denial of service and potential crash vulnerability due to a buffer overrun condition exists in the OpenSSL library used in the ICONICS Suite. This vulnerability is in the X.509 certificate name constraint checking. A denial-of-service vulnerability due to a buffer overrun condition exists in the OpenSSL library used in the ICONICS Suite. This vulnerability is in the X.509 certificate verification. A denial-of-service vulnerability due to an out of bounds read condition exists in the OpenSSL library used in the ICONICS Suite. This vulnerability is in the X.509 certificate verification. An information disclosure vulnerability due to an observable timing discrepancy exists in the OpenSSL library used in the ICONICS Suite. This vulnerability is in the RSA decryption implementation. A denial of service and potential crash vulnerability due to a double free condition exists in the OpenSSL library used in the ICONICS Suite. This vulnerability is in the reading of a PEM file. A denial of service and potential crash vulnerability due to a NULL Pointer dereference exists in the OpenSSL library used in the ICONICS Suite. This vulnerability can occur when signatures are being verified.
