Allocation of resources without limits or throttling, Uncontrolled Resource Consumption vulnerability in Legion of the Bouncy Castle Inc. BC-JAVA bcpg on all (pg modules).
This vulnerability is associated with program files AEADEncDataPacket.Java, BcAEADUtil.Java, JceAEADUtil.Java, OperatorHelper.Java.
This issue affects BC-JAVA: from 1.74 before 1.80.2, from 1.81 before 1.81.1, from 1.82 before 1.84.
A flaw was found in Legion of the Bouncy Castle Inc. BC-JAVA bcpg. A specially crafted PGP AEAD (Authenticated Encryption with Associated Data) message with an unbounded chunk size can lead to an excessive consumption of memory. This issue allows an unauthenticated remote attacker to cause memory exhaustion in a JVM, resulting in a denial of service.
Отчет
To exploit this issue, an attacker needs to submit a specially crafted PGP AEAD message containing an unbounded chunk size to an application. An attack typically requires the application to process this malformed data, resulting in the uncontrolled allocation of memory resources. The primary impact of this vulnerability is a compromise of system availability, allowing an unauthenticated remote attacker to cause memory exhaustion in a JVM, resulting in a denial of service.
Меры по смягчению последствий
To mitigate this vulnerability, enforce payload size limits on all incoming PGP messages before processing them. Additionally, apply memory quotas to the JVM or container environment to prevent a complete system outage in the event of memory exhaustion.
