Description
This security bulletin contains information about 16 secuirty vulnerabilities.
1) Resource management error (CVE-ID: CVE-2023-3817)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the application when checking the long DH keys. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
2) Unquoted Search Path or Element (CVE-ID: CVE-2025-21107)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to usage of an unquoted search path. A local user can place a malicious binary into a certain folder on the system and execute it with elevated privileges.
3) Time-of-check Time-of-use (TOCTOU) Race Condition (CVE-ID: CVE-2024-7348)
The vulnerability allows a remote user to escalate privileges within the database.
The vulnerability exists due to a race condition when executing concurrent pg_dump sessions. A remote user with privileges to create and drop non-temporary objects can execute arbitrary SQL commands with the privileges of the role running pg_dump (which is often a superuser).
4) Information disclosure (CVE-ID: CVE-2023-1786)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application. A remote attacker can gain unauthorized access to sensitive information on the system.
5) Inclusion of Sensitive Information in Log Files (CVE-ID: CVE-2021-3429)
The vulnerability allows a local user to gain access to sensitive information.
The vulnerability exists due to cloud-init writes randomly generated passwords as part of the chpasswd module into log files. A local user can read the log files and gain access to sensitive data.
6) Information disclosure (CVE-ID: CVE-2024-37891)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to Prox-Authorization header is not stripped during cross-origin redirects when using urllib3's proxy support with ProxyManager. A remote attacker can gain obtain proxy credentials used by the library.
7) Resource management error (CVE-ID: CVE-2023-5678)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within DH_generate_key() and DH_check_pub_key() functions. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
8) Resource management error (CVE-ID: CVE-2023-3446)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within the DH_check(), DH_check_ex() and EVP_PKEY_param_check() function when processing a DH key or DH parameters. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
9) OS Command Injection (CVE-ID: CVE-2022-1292)
The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation in the c_rehash script distributed by some operating systems. A remote attacker with ability to pass data to c_rehash script can and execute arbitrary OS commands with the privileges of the script.
10) Security features bypass (CVE-ID: CVE-2023-0466)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to an error within the X509_VERIFY_PARAM_add0_policy() function, which does not perform the certificate policy check despite being implicitly enabled. A remote attacker can bypass expected security restrictions and perform MitM attack.
11) Improper Verification of Cryptographic Signature (CVE-ID: CVE-2023-0465)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to an error when validating certificate policies in leaf certificates. A remote attacker that controls a malicious CA server can issue a certificate that will be validated by the application.
12) Resource exhaustion (CVE-ID: CVE-2023-0464)
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 when verifying X.509 certificate chains that include policy constraints. A remote attacker can create a specially crafted certificate to trigger resource exhaustion and perform a denial of service (DoS) attack.
13) Type Confusion (CVE-ID: CVE-2023-0286)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a type confusion error related to X.400 address processing inside an X.509 GeneralName. A remote attacker can pass specially crafted data to the application, trigger a type confusion error and perform a denial of service (DoS) attack or read memory contents.
In most cases, the attack requires the attacker to provide both the certificate chain and CRL, neither of which need to have a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. As such, this vulnerability is most likely to only affect applications which have implemented their own functionality for retrieving CRLs over a network.
14) 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.
15) 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.
16) OS Command Injection (CVE-ID: CVE-2022-2068)
The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation in the c_rehash script distributed by some operating systems. A remote attacker with ability to pass data to c_rehash script can and execute arbitrary OS commands with the privileges of the script.
The vulnerability exists due to incomplete fix for #VU62765 (CVE-2022-1292).
