Common Weakness Enumeration
CWE-789
AllowedMemory Allocation with Excessive Size Value
Abstraction: Variant · Status: Draft
The product allocates memory based on an untrusted, large size value, but it does not ensure that the size is within expected limits, allowing arbitrary amounts of memory to be allocated.
407 vulnerabilities reference this CWE, most recent first.

Summary
Rails Active Storage has a possible DoS vulnerability when in proxy mode via Range requests
Details
Impact
When serving files through Active Storage's Blobs::ProxyController, the controller loads the entire requested byte range into memory before sending it. A request with a large or unbounded Range header (e.g. bytes=0-) could cause the server to allocate memory proportional to the file size, possibly resulting in a DoS vulnerability through memory exhaustion.
Releases
The fixed releases are available at the normal locations.

Details
Archive::Tar versions before 3.10 for Perl allow memory exhaustion via attacker controlled entry size field in tar header.
_read_tar() reads each entry's payload with $handle->read($$data, $block), where $block is derived from the entry's 12-byte size field in the tar header with no upper bound on that value.
A crafted header declaring a multi-gigabyte size causes Perl to allocate a scalar of that size.

Vulnerability from github – Published: 2021-05-27 18:44 – Updated: 2023-10-02 12:27

Summary
Denial of service in Tendermint
Details
Description
Denial of Service 1
Tendermint 0.33.2 and earlier does not limit the number of P2P connection requests. For each p2p connection, Tendermint allocates XXX bytes. Even though this memory is garbage collected once the connection is terminated (due to duplicate IP or reaching a maximum number of inbound peers), temporary memory spikes can lead to OOM (Out-Of-Memory) exceptions.
Tendermint 0.33.3 (and 0.32.10) limits the total number of P2P incoming connection requests to to p2p.max_num_inbound_peers + len(p2p.unconditional_peer_ids).
Notes:
- Tendermint does not rate limit P2P connection requests per IP (an attacker can saturate all the inbound slots);
- Tendermint does not rate limit HTTP(S) requests. If you expose any RPC endpoints to the public, please make sure to put in place some protection (https://www.nginx.com/blog/rate-limiting-nginx/). We may implement this in the future (https://github.com/tendermint/tendermint/issues/1696).
Denial of Service 2
Tendermint 0.33.2 and earlier does not reclaim activeID of a peer after it's removed in Mempool reactor. This does not happen all the time. It only happens when a connection fails (for any reason) before the Peer is created and added to all reactors. RemovePeer is therefore called before AddPeer, which leads to always growing memory (activeIDs map). The activeIDs map has a maximum size of 65535 and the node will panic if this map reaches the maximum. An attacker can create a lot of connection attempts (exploiting Denial of Service 1), which ultimately will lead to the node panicking.
Tendermint 0.33.3 (and 0.32.10) claims activeID for a peer in InitPeer, which is executed before MConnection is started.
Notes:
InitPeerfunction was added to all reactors to combat a similar issue - https://github.com/tendermint/tendermint/issues/3338;- Denial of Service 2 is independent of Denial of Service 1 and can be executed without it.
Specific Go Packages Affected
github.com/tendermint/tendermint/p2p
Impact
- All full nodes (except for validators who are behind closed networks)
- Node's memory usage increases, then it panics either in the mempool or due to OOM.
Patches
- v0.33.3
- v0.32.10
- v0.31.12
Workarounds
No workarounds.

"details": "### Description\n\n**Denial of Service 1**\n\nTendermint 0.33.2 and earlier does not limit the number of P2P connection requests. For each p2p connection, Tendermint allocates XXX bytes. Even though this memory is garbage collected once the connection is terminated (due to duplicate IP or reaching a maximum number of inbound peers), temporary memory spikes can lead to OOM (Out-Of-Memory) exceptions. \n\nTendermint 0.33.3 (and 0.32.10) limits the total number of P2P incoming connection requests to to `p2p.max_num_inbound_peers + len(p2p.unconditional_peer_ids)`.\n\nNotes:\n\n- Tendermint does not rate limit P2P connection requests per IP (an attacker can saturate all the inbound slots);\n- Tendermint does not rate limit HTTP(S) requests. If you expose any RPC endpoints to the public, please make sure to put in place some protection (https://www.nginx.com/blog/rate-limiting-nginx/). We may implement this in the future (https://github.com/tendermint/tendermint/issues/1696).\n\n**Denial of Service 2**\n\nTendermint 0.33.2 and earlier does not reclaim `activeID` of a peer after it\u0027s removed in `Mempool` reactor. This does not happen all the time. It only happens when a connection fails (for any reason) before the `Peer` is created and added to all reactors. `RemovePeer` is therefore called before `AddPeer`, which leads to always growing memory (`activeIDs` map). The `activeIDs` map has a maximum size of 65535 and the node will panic if this map reaches the maximum. An attacker can create a lot of connection attempts (exploiting Denial of Service 1), which ultimately will lead to the node panicking.\n\nTendermint 0.33.3 (and 0.32.10) claims `activeID` for a peer in `InitPeer`, which is executed before `MConnection` is started.\n\nNotes: \n\n- `InitPeer` function was added to all reactors to combat a similar issue - https://github.com/tendermint/tendermint/issues/3338;\n- Denial of Service 2 is independent of Denial of Service 1 and can be executed without it.\n\n### Specific Go Packages Affected\ngithub.com/tendermint/tendermint/p2p\n\n### Impact\n\n- All full nodes (except for validators who are behind closed networks)\n- Node\u0027s memory usage increases, then it panics either in the mempool or due to OOM.\n\n### Patches\n\n- v0.33.3\n- v0.32.10\n- v0.31.12\n\n### Workarounds\n\nNo workarounds.\n\n### References\n\n- https://hackerone.com/reports/820317 (not disclosed yet)\n- https://github.com/tendermint/tendermint/issues/3338\n- https://github.com/tendermint/tendermint/issues/1696\n\n### For more information\n\nIf you have any questions or comments about this advisory:\n* Open an issue in [tendermint/tendermint](https://github.com/tendermint/tendermint)\n* Email us at [security@tendermint.com](mailto:security@tendermint.com)\n\nMore information can be found [here](https://tendermint.com/security/).\n\n### Credits\n\n- [fudongbai](https://hackerone.com/fudongbai) for discovering and reporting Denial of Service 2\n- Ethan Buchman (@ebuchman) for writing a test case for Denial of Service 2 and Tess Rinearson (@tessr) for fixing it\n- Anton Kaliaev (@melekes) for fixing Denial of Service 1",

Vulnerability from github – Published: 2026-03-31 12:31 – Updated: 2026-03-31 12:31
VLAI
Details
An attacker might be able to trick DNSdist into allocating too much memory while processing DNS over QUIC or DNS over HTTP/3 payloads, resulting in a denial of service. In setups with a large quantity of memory available this usually results in an exception and the QUIC connection is properly closed, but in some cases the system might enter an out-of-memory state instead and terminate the process.

5.3 (Medium)

}
Mitigation
Implementation
Architecture and Design
Perform adequate input validation against any value that influences the amount of memory that is allocated. Define an appropriate strategy for handling requests that exceed the limit, and consider supporting a configuration option so that the administrator can extend the amount of memory to be used if necessary.
Mitigation
Operation
Run your program using system-provided resource limits for memory. This might still cause the program to crash or exit, but the impact to the rest of the system will be minimized.
