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.
406 vulnerabilities reference this CWE, most recent first.

Title
psd-tools: Compression module has unguarded zlib decompression, missing dimension validation, and hardening gaps
Summary
psd-tools is a Python package for working with Adobe Photoshop PSD files. Prior to version 1.12.2, when a PSD file contains malformed RLE-compressed image data (e.g. a literal run that extends past the expected row size), decode_rle() raises ValueError which propagated all the way to the user, crashing psd.composite() and psd-tools export. decompress() already had a fallback that replaces failed channels with black pixels when result is None, but it never triggered because the ValueError from decode_rle() was not caught. The fix in version 1.12.2 wraps the decode_rle() call in a try/except so the existing fallback handles the error gracefully.

Title
Wasmtime WASI implementations are vulnerable to guest-controlled resource exhaustion
Summary
Wasmtime is a runtime for WebAssembly. Prior to versions 24.0.6, 36.0.6, 4.0.04, 41.0.4, and 42.0.0, Wasmtime's implementation of WASI host interfaces are susceptible to guest-controlled resource exhaustion on the host. Wasmtime did not appropriately place limits on resource allocations requested by the guests. This serves as a Denial of Service vector. Wasmtime 24.0.6, 36.0.6, 40.0.4, 41.0.4, and 42.0.0 have all been released with the fix for this issue. These versions do not prevent this issue in their default configuration to avoid breaking preexisting behaviors. All versions of Wasmtime have appropriate knobs to prevent this behavior, and Wasmtime 42.0.0-and-later will have these knobs tuned by default to prevent this issue from happening. There are no known workarounds for this issue without upgrading. Embedders are recommended to upgrade and configure their embeddings as necessary to prevent possibly-malicious guests from triggering this issue.

Title
Memory allocation with excessive without limits in the internal SVG decoder
Summary
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a crafted SVG file containing an malicious element causes ImageMagick to attempt to allocate ~674 GB of memory, leading to an out-of-memory abort. Versions 7.1.2-15 and 6.9.13-40 contain a patch.

Title
Fiber is Vulnerable to Denial of Service via Flash Cookie Unbounded Allocation
Summary
Fiber is an Express inspired web framework written in Go. In versions on the v3 branch prior to 3.1.0, the use of the `fiber_flash` cookie can force an unbounded allocation on any server. A crafted 10-character cookie value triggers an attempt to allocate up to 85GB of memory via unvalidated msgpack deserialization. No authentication is required. Every GoFiber v3 endpoint is affected regardless of whether the application uses flash messages. Version 3.1.0 fixes the issue.

Title
Navidrome affected by Denial of Service and disk exhaustion via oversized `size` parameter in `/rest/getCoverArt` and `/share/img/<token>` endpoints
Summary
Navidrome is an open source web-based music collection server and streamer. Prior to version 0.60.0, authenticated users can crash the Navidrome server by supplying an excessively large size parameter to /rest/getCoverArt or to a shared-image URL (/share/img/<token>). When processing such requests, the server attempts to create an extremely large resized image, causing uncontrolled memory growth. This triggers the Linux OOM killer, terminates the Navidrome process, and results in a full service outage. If the system has sufficient memory and survives the allocation, Navidrome then writes these extremely large resized images into its cache directory, allowing an attacker to rapidly exhaust server disk space as well. This issue has been patched in version 0.60.0.

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.
