UBUNTU-CVE-2023-0216

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...

X.509 Name Constraints Read Buffer Overflow

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...

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. If the function succeeds then the “nameout”, “header” and “data” arguments are populated with pointers to buffers containing the relevant decoded data...

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...

Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS : OpenSSL vulnerabilities (USN-5844-1)

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5844-1 advisory. David Benjamin discovered that OpenSSL incorrectly handled X.400 address processing. A remote attacker could possibly use this...

Important: openssl

Issue Overview: A timing-based side channel exists in the OpenSSL RSA Decryption implementation, which could be sufficient to recover a ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption, an attacker would have to be able to send a very large number o...

OpenSSL 1.1.1 < 1.1.1t Multiple Vulnerabilities

The version of OpenSSL installed on the remote host is prior to 1.1.1t. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.1.1t advisory. - There is a type confusion vulnerability relating to X.400 address processing inside an X.509 GeneralName. X.400 addresses were...

Use-after-free following BIO_new_NDEF

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...

NULL dereference during PKCS7 data verification

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...

Ubuntu 18.04 LTS : OpenSSL vulnerabilities (USN-5845-1)

The remote Ubuntu 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5845-1 advisory. David Benjamin discovered that OpenSSL incorrectly handled X.400 address processing. A remote attacker could possibly use this issue to read arbitrary...

UBUNTU-CVE-2023-0286

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...

Use-After-Free

openssl is vulnerable to Use-After-Free. The vulnerability exists because there is a missing check for the return value from the initialization function which allows an attacker to cause an application crash...
