Background
libxstream-java is a library that allows for the serialization and deserialization of Java objects to XML and vice versa. It is commonly used in Java applications to facilitate data exchange and storage. However, versions prior to 1.4.15-3+deb11u2 are susceptible to a stack overflow vulnerability that can be exploited remotely. This vulnerability arises from a flaw in the hash code implementation for collections and maps, which can be manipulated to force recursive hash calculation, resulting in a stack overflow error. This can lead to a denial of service, causing the application to terminate unexpectedly.
Vulnerability Detail
The vulnerability in libxstream-java arises from a stack overflow error that can be triggered by a remote attacker through manipulation of the input stream. By exploiting the flawed hash code implementation, the attacker can force recursive hash calculation, overwhelming the stack and causing the application to crash. This denial of service attack can disrupt the normal functioning of the application and potentially impact its availability. The vulnerability has been assigned the identifier CVE-2022-41966.
