GHSA-M8VF-G949-JWR2
Vulnerability from github – Published: 2026-03-25 18:31 – Updated: 2026-03-25 18:31
VLAI
Details
A vulnerability in the DHCP snooping feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause BOOTP packets to be forwarded between VLANs, resulting in a denial of service (DoS) condition.
This vulnerability is due to improper handling of BOOTP packets on Cisco Catalyst 9000 Series Switches. An attacker could exploit this vulnerability by sending BOOTP request packets to an affected device. A successful exploit could allow an attacker to forward BOOTP packets from one VLAN to another, resulting in BOOTP VLAN leakage and potentially leading to high CPU utilization. This makes the device unreachable (either through console or remote management) and unable to forward traffic, resulting in a DoS condition.
Note: This vulnerability can be exploited with either unicast or broadcast BOOTP packets.
There are workarounds that address this vulnerability.

Details
The deflate_in_filter function in mod_deflate.c in the mod_deflate module in the Apache HTTP Server before 2.4.10, when request body decompression is enabled, allows remote attackers to cause a denial of service (resource consumption) via crafted request data that decompresses to a much larger size.

GHSA-M92W-X6J2-5GC5
Vulnerability from github – Published: 2025-03-01 00:31 – Updated: 2026-02-10 18:30
VLAI
Details
A flaw was found in the OpenSSH package. For each ping packet the SSH server receives, a pong packet is allocated in a memory buffer and stored in a queue of packages. It is only freed when the server/client key exchange has finished. A malicious client may keep sending such packages, leading to an uncontrolled increase in memory consumption on the server side. Consequently, the server may become unavailable, resulting in a denial of service attack.

GHSA-M974-XJ4J-7QV5
Vulnerability from github – Published: 2023-05-11 20:32 – Updated: 2023-05-11 20:32

Summary
Boxo bitswap/server: DOS unbounded persistent memory leak
Details
Impact
An attacker is able allocate arbitrarily many bytes in the Bitswap server by sending many WANT_BLOCK and or WANT_HAVE requests which are queued in an unbounded queue, with allocations that persist even if the connection is closed.
This affects users accepting untrusted connections with the Bitswap server, this also affects users using the old API stubs at github.com/ipfs/boxo/bitswap because it transitively uses github.com/ipfs/boxo/bitswap/server.
We have renamed go-libipfs to boxo; this document uses both terms interchangeably. The version numbers for both are applicable, as they share the same historical timeline.
Remediation
Apply one of:
- Update boxo to v0.6.0 or later
- Update boxo to v0.4.1
Note that v0.5.0 is NOT safe, v0.4.1 is a backport of the v0.6.0 security fixes on top of v0.4.0.
Mitigations
- The server now limits how many wantlist entries per peer it knows.
The
MaxQueuedWantlistEntriesPerPeeroption allows configuring how many wantlist entries the server remembers; if a peer sends a wantlist bigger than this (including a sum of multiple delta updates) the server will truncate the wantlist to the match the limit. This defaults to1024entries per peer. - The server now properly clears state about peers when they disconnect.
Peer state is more lazily allocated (only when a wantlist is received in the first place) and is properly cleared when the
PeerDisconnectedcallback is received. - The server now ignores CIDs above some size.
Clients were able to send any CID as long as the total protobuf message were bellow the 4MiB limit. This is allowed to allocate lots of memory with very little entries.
This can be configured using the
MaxCidSizeoption and defaults to168 bytes. - The server now closes the connection if an inline CID is requested (either as
WANT_*orCANCEL). The attack were more effective if done with CIDs that are present in target's blockstore, this is because this will push longer-lasting jobs on some priority queue. Since inline CID are literal data (instead of hashes of data), everyone always "has" any inline CID (since instead of loading the data from disk, it can be extracted from the CID). It makes no sense for anyone to ever ask you about an inline CID since they could also just parse it themselves. Thus, as a defensive measure, we kill the connection with peers that ask about an inline CID.

Workarounds
If you are using the stubs at github.com/ipfs/go-libipfs/bitswap and not taking advantage of the features provided by the server, refactoring your code to use the new split API will allow you to run in a client-only mode using: github.com/ipfs/boxo/bitswap/client.

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.
