Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2022-41723)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources in the HPACK decoder. A remote attacker can send a specially crafted HTTP/2 stream to the application, cause resource exhaustion and perform a denial of service (DoS) attack.
2) Inadequate Encryption Strength (CVE-ID: CVE-2023-3089)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists within the OpenShift container platform configuration with enabled FIPS mode, which resulted in usage of not validated cryptographic modules. A remote attacker can perform various attacks against not validated cryptographic modules and gain access to sensitive information.
3) Buffer overflow (CVE-ID: CVE-2020-24736)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when executing a crafted SELECT query. A local user can execute a specially crafted query to trigger memory corruption and perform a denial of service (DoS) attack.
4) 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.
5) 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.
6) 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.
7) Inadequate Encryption Strength (CVE-ID: CVE-2023-0361)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to an error in the TLS RSA key exchange. A remote attacker can perform Bleichenbacher oracle attack and decrypt information.
8) Input validation error (CVE-ID: CVE-2023-1667)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to multiple errors in kex implementation, related to kex guessing algorithm. A remote attacker can bypass implemented security restrictions.
9) Improper Authentication (CVE-ID: CVE-2023-2283)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error within the pki_verify_data_signature() function in pki_crypto.c. The pki_key_check_hash_compatible() function can return SSH_OK value if memory allocation error happens later in the function. The A remote attacker can bypass authentication process and gain unauthorized access to the system.
10) Input validation error (CVE-ID: CVE-2023-24329)
The vulnerability allows a remote attacker to bypass implemented filters.
The vulnerability exists due to insufficient validation of URLs that start with blank characters within urllib.parse component of Python. A remote attacker can pass specially crafted URL to bypass existing filters.
11) Improper Privilege Management (CVE-ID: CVE-2023-26604)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper privilege management for some Sudo configurations, e.g., plausible sudoers files in which the "systemctl status" command may be executed. Specifically, systemd does not set LESSSECURE to 1, and thus other programs may be launched from the less program. This presents a substantial security risk when running systemctl from Sudo, because less executes as root when the terminal size is too small to show the complete systemctl output.
