All versions of the package images are vulnerable to Denial of Service (DoS) due to providing unexpected input types to several different functions. This makes it possible to reach an assert macro, leading to a process crash. Note: By providing some specific integer values (like 0) to the size function, it is possible to obtain a Segmentation fault error, leading to the process crash.
The product does not properly control the allocation and maintenance of a limited resource.
Mitigation of resource exhaustion attacks requires that the target system either:
The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
The second solution is simply difficult to effectively institute – and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
