Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Missing Encryption of Sensitive Data (CVE-ID: CVE-2022-2097)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to an error in AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimized implementation. Under specific circumstances OpenSSL does not encrypt the entire message and can reveal sixteen bytes of data that was preexisting in the memory that wasn't written. A remote attacker can gain access to potentially sensitive information.



2) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2022-4304)

The vulnerability allows a remote attacker to obtain sensitive information.

The vulnerability exists due to a timing based side channel exists in the OpenSSL RSA Decryption implementation. A remote attacker can perform a Bleichenbacher style attack and decrypt data sent over the network.

To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE.


3) Double Free (CVE-ID: CVE-2022-4450)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error within the PEM_read_bio_ex() function. A remote attacker can pass specially crafted PEM file to the application, trigger a double free error and perform a denial of service (DoS) attack.


4) Use-after-free (CVE-ID: CVE-2023-0215)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a use-after-free error within the BIO_new_NDEF function. A remote attacker can trigger a use-after-free error and perform a denial of service (DoS) attack.
