CWE-789

Allowed

Memory Allocation with Excessive Size Value

Abstraction: Variant · Status: Draft

API response cwe.mitre.org

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.

511 vulnerabilities reference this CWE, most recent first.

Title
Xerial snappy-java before 1.1.10.9 Unbounded Memory Allocation Denial of Service
Summary
Xerial snappy-java before 1.1.10.9 contains an unbounded memory allocation vulnerability that allows attackers to exhaust JVM memory by declaring a large uncompressed length in compressed input. Attackers can supply a few crafted bytes to Snappy.uncompress, uncompressString, SnappyInputStream or SnappyFramedInputStream to force allocations up to 2 GB, causing OutOfMemoryError and denial of service.

CVE-2026-107390 (GCVE-0-2026-107390)

Title
music-metadata: MP4 parser allows memory exhaustion via oversized extended atom length
Summary
music-metadata is a metadata parser for audio and video media files. Prior to 11.16.0, the MP4 parser accepts an attacker-controlled 64-bit extended atom size, converts it to a JavaScript Number, and uses the resulting payload length for atom-specific readToken calls before proving that the atom fits within its parent or the available input. A tiny MP4-family file can route an oversized length into payload parsing for atoms including mvhd, stsd, stsz, and date, causing a large allocation attempt or process failure before end-of-input validation. Applications that parse untrusted MP4-family media can therefore be denied service. This issue is fixed in version 11.16.0.

CVE-2026-107389 (GCVE-0-2026-107389)

Vulnerability from cvelistv5 – Published: 2026-10-08 19:05 – Updated: 2026-10-09 18:32

Title
music-metadata: EBML parser trusts element lengths, allowing memory exhaustion or process abort
Summary
music-metadata is a metadata parser for audio and video media files. Prior to 11.16.0, the Matroska and WebM EBML parser decodes an attacker-controlled VINT element length and uses it for string-token or Uint8Array allocation before confirming that the leaf fits within its parent or available input. Crafted WebM, MKV, or MKA inputs can cause disproportionate allocations, out-of-memory denial of service, or, for a demonstrated parseFile path on Node.js 26.7.0, an uncatchable V8 fatal abort. The exact failure mode depends on the tokenizer, parser API, and runtime, but the affected leaf-length validation flaw is shared and has availability impact only. This issue is fixed in version 11.16.0.

Crafted WebM, MKV, or MKA inputs can cause disproportionate allocations, out-of-memory denial of service, or, for a demonstrated parseFile path on Node.js 26.7.0, an uncatchable V8 fatal abort. The exact failure mode depends on the tokenizer, parser API, and runtime, but the affected leaf-length validation flaw is shared and has availability impact only.

Title
music-metadata: ID3v2 tag size not validated before allocation, causing memory exhaustion DoS
Summary
music-metadata is a metadata parser for audio and video media files. Prior to 11.16.0, the ID3v2 parser trusts the syncsafe tag-size field and allocates the complete tag body before checking whether the input contains the declared bytes. A truncated file containing only an ID3v2 header can request an allocation approaching 268 MiB; the allocation succeeds, the subsequent read reaches end of stream, the EndOfStreamError is caught internally, and the caller receives a normal metadata object. This issue is fixed in version 11.16.0.

Title
music-metadata: Uncontrolled memory allocation in APEv2 parser
Summary
music-metadata is a metadata parser for audio and video media files. Prior to 11.16.0, the APEv2 parser reads an attacker-controlled tag-item size and allocates a Uint8Array for a binary item before proving that the declared item fits in the remaining tag or file data. A small crafted APE file can therefore trigger a disproportionate allocation, including through cover-art items, and repeated or concurrent parsing can exhaust process memory. The demonstrated impact is availability loss only. This issue is fixed in version 11.16.0.

CVE-2026-107223 (GCVE-0-2026-107223)

Vulnerability from cvelistv5 – Published: 2026-10-07 18:48 – Updated: 2026-10-07 22:05

Title
Excelize: Unbounded <col max> attribute is loaded with no MaxColumns check and expanded per-column by flatCols(), so any column mutator hangs or OOMs the process
Summary
Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.1.0 to 2.11.0, flatCols expands file-loaded column ranges without validating Min and Max against the worksheet column limit. SetColWidth reaches flatCols, which expands xlsxCol.Min through xlsxCol.Max without enforcing MaxColumns. When a crafted worksheet supplies an oversized col max attribute and the application invokes a column mutator, flatCols performs a deep copy and append for every attacker-selected column number, allowing an attacker to consume excessive CPU and memory or trigger OOM. No fixed version is available as of this review.

CVE-2026-107215 (GCVE-0-2026-107215)

Vulnerability from cvelistv5 – Published: 2026-10-07 17:48 – Updated: 2026-10-10 02:38

Title
Excelize: extractPart allocates attacker-controlled, unbounded and negative-sized buffers from CFB directory entries: remote panic / OOM DoS
Summary
Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.3.1 to 2.11.0, extractPart allocates a byte slice directly from an attacker-controlled CFB directory-entry size before validating the sector chain or size domain. extractPart trusts the CFB directory entry streamSize for EncryptionInfo and EncryptedPackage allocations before validating the stream. When a crafted OLE compound file declares a negative or extremely large EncryptionInfo or EncryptedPackage stream size, the declared size reaches make with a negative length or forces a multi-gigabyte allocation, allowing an attacker to panic or exhaust process memory. No fixed version is available as of this review.

Title
ImageMagick: Denial of service in ASE decoder because of missing security checks
Summary
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-32, missing validation and resource checks in the ASE decoder allow a crafted ASE image to cause a crash or a long-running operation. This issue is fixed in version 7.1.2-32.

CVE-2026-106453 (GCVE-0-2026-106453)

Vulnerability from cvelistv5 – Published: 2026-10-06 19:54 – Updated: 2026-10-07 17:07

Title
yawkat LZ4 Java: LZ4DecompressorWithLength allocates the unvalidated size from the 4-byte length header, so a 5-byte input triggers a 1 GiB allocation and OutOfMemoryError
Summary
yawkat LZ4 Java provides LZ4 compression for Java. Prior to 1.11.2, LZ4DecompressorWithLength uses getDecompressedLength to trust the four-byte decompressed-length header before validating the compressed input, allowing a five-byte attacker-supplied input whose header declares a large output size to request up to approximately 2 GiB and exhaust the JVM heap. Convenience overloads backed by LZ4FastDecompressor or LZ4SafeDecompressor allocate the untrusted size, while overloads that write to a caller-provided destination buffer are not affected because the caller controls the destination size. This issue is fixed in version 1.11.2.

CVE-2026-106452 (GCVE-0-2026-106452)

Title
yawkat LZ4 Java: LZ4BlockInputStream allocates an unvalidated compressed length from the stream header
Summary
yawkat LZ4 Java provides LZ4 compression for Java. Prior to 1.11.2, net.jpountz.lz4.LZ4BlockInputStream refill() validates that the compressedLen field in a legacy LZ4Block header is nonnegative but allocates a compressed-input buffer of that attacker-controlled size before reading payload data, allowing a header-only stream to request a near-2 GiB allocation and exhaust the JVM heap. Canonical writers emit raw blocks when compression is not smaller than the original block, but vulnerable readers accept non-canonical oversized compressed blocks. This issue is fixed in version 1.11.2.

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.
