Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Error Handling (CVE-ID: CVE-2022-45142)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to a logic issue in Heimdal GSSAPI related to patch for vulnerability #VU68701 (CVE-2022-3437). A remote user can perform a denial of service (DoS) attack.
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.
