Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Information Exposure Through Timing Discrepancy (CVE-ID: CVE-2021-38153)

The vulnerability allows a local user to escalate privileges on the system.

the vulnerability exists due to some components in Apache Kafka use "Arrays.equals" to validate a password or key, which is vulnerable to timing attacks. A local user can abuse the "Arrays.equals" to brute force access credentials and escalate privileges on the system.


2) Out-of-bounds read (CVE-ID: CVE-2021-3712)

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

The vulnerability exists due to a boundary condition when processing ASN.1 strings related to a confusion with NULL termination of strings in array. A remote attacker can pass specially crafted data to the application to trigger an out-of-bounds read error and read contents of memory on the system or perform a denial of service (DoS) attack.


3) Missing Encryption of Sensitive Data (CVE-ID: CVE-2021-23222)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to the way the libpq process in PostgreSQL handles encrypted connections. A man-in-the-middle attacker can inject false responses to the client's first few queries, despite the use of SSL certificate verification and encryption. The attacker can exfiltrate the client's password or other confidential data that might be transmitted early in a session.


4) Memory leak (CVE-ID: CVE-2021-3677)

The vulnerability allows a remote user to perform DoS attack or gain access to sensitive information.

The vulnerability exists due memory leak during parallel sort operations. A remote user can force the application to leak memory and perform denial of service attack or read arbitrary memory parts on the system.
