Vulnerability from github – Published: 2020-10-16 17:03 – Updated: 2021-10-04 21:26
VLAI
Summary
Memory exhaustion in http4s-async-http-client with large or malicious compressed responses
Details

Impact

A server we connect to with http4s-async-http-client could theoretically respond with a large or malicious compressed stream and exhaust memory in the client JVM. It does not affect http4s servers, other client backends, or clients that speak only to trusted servers. This is related to a transitive dependency on netty-codec-4.1.45.Final, which is affected by CVE-2020-11612.

Patches

Upgrade to http4s-async-http-client >= 0.21.8. All 1.0 milestones are also safe.

Workarounds

Add an explicit runtime dependency on async-http-client's netty dependencies that evicts them to an unaffected version:

libraryDependencies ++= Seq(
  "io.netty" %  "netty-codec"         % "4.1.53.Final" % Runtime,
  "io.netty" %  "netty-codec-socks"   % "4.1.53.Final" % Runtime,
  "io.netty" %  "netty-handler-proxy" % "4.1.53.Final" % Runtime,
  "io.netty" %  "netty-common"        % "4.1.53.Final" % Runtime,
  "io.netty" %  "netty-transport"     % "4.1.53.Final" % Runtime,
  "io.netty" %  "netty-handler"       % "4.1.53.Final" % Runtime,
  "io.netty" %  "netty-resolver-dns"  % "4.1.53.Final" % Runtime
)

Vulnerability from github – Published: 2026-07-15 22:05 – Updated: 2026-08-17 16:15
VLAI
Summary
websocket-driver: Memory exhaustion in HTTP header parser
Details

Impact

If this library is used to implement a WebSocket server on top of a TCP server (rather than an HTTP server or framework) using the WebSocket::Driver.server() method, or, if it is used to complement a WebSocket client, then a peer can make a single connection consume an unbounded amount of memory by sending an HTTP request or response with a never-ending list of headers. This can lead to the receiving process running out of memory.

Patches

The issue has been patched in version 0.8.1, by limiting the total size of HTTP request/response lines and headers accepted by the parser to 32 kB. All users should upgrade to this version.

Workarounds

No known workarounds exist.

Acknowledgements

This issue was discovered and reported by Pranjali Thakur, DepthFirst Security Research Team.

Vulnerability from github – Published: 2019-08-27 17:45 – Updated: 2021-08-17 22:18
VLAI
Summary
Prototype Pollution in deeply
Details

Versions of deeply prior to 1.0.1 are vulnerable to Prototype Pollution. The package fails to validate which Object properties it updates. This allows attackers to modify the prototype of Object, causing the addition or modification of an existing property on all objects.

Recommendation

Upgrade to version 3.1.0 or later.

Vulnerability from github – Published: 2020-11-11 21:38 – Updated: 2020-11-11 21:38
VLAI
Summary
Exploitable inventory component chaining in PocketMine-MP
Details

Impact

Specially crafted InventoryTransactionPackets sent by malicious clients were able to exploit the behaviour of InventoryTransaction->findResultItem() and cause it to take an abnormally long time to execute (causing an apparent server freeze).

The affected code is intended to compact conflicting InventoryActions which are in the same InventoryTransaction by flattening them into a single action. When multiple pathways to a result existed, the complexity of this flattening became exponential.

The problem was fixed by bailing when ambiguities are detected.

At the time of writing, this exploit is being used in the wild by attackers to deny service to servers.

Patches

Upgrade to 3.15.4 or newer.

Workarounds

No practical workarounds are possible, short of backporting the fix or implementing checks in a plugin listening to DataPacketReceiveEvent.

Mitigation
Architecture and Design

Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended. A strong authentication and access control model will help prevent such attacks from occurring in the first place. The login application should be protected against DoS attacks as much as possible. Limiting the database access, perhaps by caching result sets, can help minimize the resources expended. To further limit the potential for a DoS attack, consider tracking the rate of requests received from users and blocking requests that exceed a defined rate threshold.

Mitigation
Architecture and Design
  • 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.
  • recognizes the attack and denies that user further access for a given amount of time, or
  • uniformly throttles all requests in order to make it more difficult to consume resources more quickly than they can again be freed.
Mitigation
Architecture and Design

Ensure that protocols have specific limits of scale placed on them.

Mitigation
Implementation

Ensure that all failures in resource allocation place the system into a safe posture.

CAPEC-147: XML Ping of the Death

An attacker initiates a resource depletion attack where a large number of small XML messages are delivered at a sufficiently rapid rate to cause a denial of service or crash of the target. Transactions such as repetitive SOAP transactions can deplete resources faster than a simple flooding attack because of the additional resources used by the SOAP protocol and the resources necessary to process SOAP messages. The transactions used are immaterial as long as they cause resource utilization on the target. In other words, this is a normal flooding attack augmented by using messages that will require extra processing on the target.

CAPEC-227: Sustained Client Engagement

An adversary attempts to deny legitimate users access to a resource by continually engaging a specific resource in an attempt to keep the resource tied up as long as possible. The adversary's primary goal is not to crash or flood the target, which would alert defenders; rather it is to repeatedly perform actions or abuse algorithmic flaws such that a given resource is tied up and not available to a legitimate user. By carefully crafting a requests that keep the resource engaged through what is seemingly benign requests, legitimate users are limited or completely denied access to the resource.

CAPEC-492: Regular Expression Exponential Blowup

An adversary may execute an attack on a program that uses a poor Regular Expression(Regex) implementation by choosing input that results in an extreme situation for the Regex. A typical extreme situation operates at exponential time compared to the input size. This is due to most implementations using a Nondeterministic Finite Automaton(NFA) state machine to be built by the Regex algorithm since NFA allows backtracking and thus more complex regular expressions.
