Common Weakness Enumeration

CWE-190

Allowed

Integer Overflow or Wraparound

Abstraction: Base · Status: Stable

The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.

4667 vulnerabilities reference this CWE, most recent first.

GHSA-FW94-4WWP-W8PW

Vulnerability from github – Published: 2026-10-07 20:22 – Updated: 2026-10-07 20:22

Summary

Excelize: A Zip64 uncompressed-size of 2^63 panics OpenFile/OpenReader

Details

Summary

A Zip64 uncompressed-size of 2^63 casts to a negative int64 that bypasses the unzip-size guard and reaches make([]byte, 0, negativeCap)

A Zip64 uncompressed-size in the range [2^63, 2^64) casts to a negative int64 in zip.File.FileInfo().Size(), and ReadZipReader does signed arithmetic on that value, so the total-decompression guard is bypassed and the negative size reaches make([]byte, 0, size) in readFile. A 159-byte crafted file panics OpenFile and OpenReader with runtime error: makeslice: cap out of range.

The guard, at lib.go:44-46 on HEAD ae2113b:

fileSize := v.FileInfo().Size()
unzipSize += fileSize
if unzipSize > f.options.UnzipSizeLimit {
    return fileList, worksheets, newUnzipSizeLimitError(f.options.UnzipSizeLimit)
}

FileInfo().Size() returns int64(UncompressedSize64). UncompressedSize64 is read from the Zip64 extended-information extra record in the central directory and is fully attacker controlled, so any value with the top bit set arrives as a negative int64. unzipSize then goes negative and the comparison against UnzipSizeLimit (default 1000 << 24, templates.go:193) is false no matter how many such entries the archive contains.

The same negative value also fails the two stream-to-temp checks at lib.go:53 and lib.go:64 (fileSize > f.options.UnzipXMLSizeLimit), so the entry is not diverted to a temp file and control reaches readFile:

// lib.go:150
dat := make([]byte, 0, file.FileInfo().Size())

make with a negative capacity panics. There is no recover() in any non-test file in the library, so the panic leaves the public API and takes down the calling goroutine.

The asymmetry inside this same function is the clearest way to see it: unzipToTemp (lib.go:83) handles an entry with a plain io.Copy and never pre-allocates from the declared size, so it is indifferent to whatever the header claims. Only the pre-allocating branch trusts that number, and it trusts it after a signed comparison that a wrapped value walks straight through.

Reproduction, executed against HEAD `ae2113b` (go1.26.5)

A 159-byte archive was built with one stored entry named xl/worksheets/sheet1.xml: truthful 1-byte local header, central-directory 32-bit uncompressed size set to the 0xFFFFFFFF Zip64 sentinel, and a Zip64 extra record (tag 0x0001, data size 8) declaring UncompressedSize64 = 0x8000000000000000.

entry "xl/worksheets/sheet1.xml" FileInfo().Size() = -9223372036854775808
excelize.OpenReader(bytes.NewReader(raw))  ->  panic: runtime error: makeslice: cap out of range

Control, the identical archive with UncompressedSize64 = 0x7FFFFFFFFFFFFFFF:

entry "xl/worksheets/sheet1.xml" FileInfo().Size() = 9223372036854775807
excelize.OpenReader(bytes.NewReader(raw))  ->  err = "unzip size exceeds the 16777216000 bytes limit"

The control isolates the defect to the sign flip rather than to size magnitude: the guard behaves correctly for any positive declared size and fails only once the value wraps. archive/zip itself accepts the archive without complaint, so nothing upstream of excelize rejects it.

What I verified and what I did not

I ran both cases above myself and confirmed each cited line at HEAD. I caught the panic with a deliberate recover in my harness so I could print it; nothing in excelize recovers it, which I checked by grepping every non-test .go file. I did not separately run the OpenFile variant, since OpenFile reaches the same ReadZipReader loop, and I did not attempt to turn the bypassed size cap into a separate decompression-bomb primitive.

Attacker model

Any service that opens a spreadsheet it did not produce. The payload is 159 bytes, needs no authentication, and is deterministic.

Suggested fix

Compare against the limit in unsigned space, and bound the allocation independently rather than trusting the header:

if v.UncompressedSize64 > uint64(f.options.UnzipSizeLimit) {
    return fileList, worksheets, newUnzipSizeLimitError(f.options.UnzipSizeLimit)
}

and in readFile, reject or clamp a declared size that is negative or larger than the limit before calling make. The same unsigned treatment applies to the two UnzipXMLSizeLimit comparisons, which currently route a wrapped size away from the safe streaming path and into the pre-allocating one.

Severity

6.5 (Medium)

Advisory FAQ

How do I know if I am affected?

If using a package listed in affected packages, an application is exposed to the vulnerability.

How do I fix the issue?

To fix the issue please install the latest version of .NET. If users have installed one or more .NET SDKs through Visual Studio, Visual Studio will prompt them to update Visual Studio, which will also update their .NET SDKs.
If a user's application references the vulnerable package, update the package reference to the patched version. Users can list the versions they have installed by running the dotnet --info command.

Once users have installed the updated runtime or SDK, they should restart their apps for the update to take effect.

Additionally, if they've deployed self-contained applications targeting any of the impacted versions, these applications are also vulnerable and must be recompiled and redeployed.

Mitigation

Requirements

Ensure that all protocols are strictly defined, such that all out-of-bounds behavior can be identified simply, and require strict conformance to the protocol.

Mitigation MIT-3

Requirements

Strategy: Language Selection

Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
If possible, choose a language or compiler that performs automatic bounds checking.

Mitigation MIT-4

Architecture and Design

Strategy: Libraries or Frameworks

Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid [REF-1482].
Use libraries or frameworks that make it easier to handle numbers without unexpected consequences.
Examples include safe integer handling packages such as SafeInt (C++) or IntegerLib (C or C++). [REF-106]

Mitigation MIT-8

Implementation

Strategy: Input Validation

Perform input validation on any numeric input by ensuring that it is within the expected range. Enforce that the input meets both the minimum and maximum requirements for the expected range.
Use unsigned integers where possible. This makes it easier to perform validation for integer overflows. When signed integers are required, ensure that the range check includes minimum values as well as maximum values.

Mitigation MIT-36

Implementation

Understand the programming language's underlying representation and how it interacts with numeric calculation (CWE-681). Pay close attention to byte size discrepancies, precision, signed/unsigned distinctions, truncation, conversion and casting between types, "not-a-number" calculations, and how the language handles numbers that are too large or too small for its underlying representation. [REF-7]
Also be careful to account for 32-bit, 64-bit, and other potential differences that may affect the numeric representation.

Mitigation MIT-15

Architecture and Design

For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.

Mitigation MIT-26

Implementation

Strategy: Compilation or Build Hardening

Examine compiler warnings closely and eliminate problems with potential security implications, such as signed / unsigned mismatch in memory operations, or use of uninitialized variables. Even if the weakness is rarely exploitable, a single failure may lead to the compromise of the entire system.

CAPEC-92: Forced Integer Overflow

This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.
