Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Stack-based buffer overflow (CVE-ID: CVE-2022-38752)

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

The vulnerability exists due to a boundary error when handling YAML files. A remote attacker can pass a specially crafted YAML file to the application, trigger a stack-based buffer overflow and perform a denial of service (DoS) attack.


2) Deserialization of Untrusted Data (CVE-ID: CVE-2022-42003)

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

The vulnerability exists due to insecure input validation when processing serialized data when the UNWRAP_SINGLE_VALUE_ARRAYS feature is enabled. A remote attacker can pass specially crafted data to the application and cause a denial of service condition on the target system.


3) Unchecked Return Value (CVE-ID: CVE-2022-1319)

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

The vulnerability exists due to EAP 7 improperly sends two response packets, and those packets have the reuse flag set even though JBoss EAP closes the connection. A remote attacker can trigger the vulnerability to perform a denial of service attack.

4) Input validation error (CVE-ID: CVE-2022-3171)

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

The vulnerability exists due to insufficient validation of user-supplied input containing multiple instances of non-repeated embedded messages with repeated or unknown fields. A remote attacker can cause objects to be converted back-n-forth between mutable and immutable forms, resulting in potentially long garbage collection pauses.


5) Improper Authorization (CVE-ID: CVE-2022-31692)

The vulnerability allows a remote attacker to bypass authorization checks.

The vulnerability exists due to authorization rules bypass via forward or include dispatcher types. A remote attacker can bypass authorization process.
