CWE-190
AllowedInteger 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.
3870 vulnerabilities reference this CWE, most recent first.

GHSA-FJPJ-2G6W-X25R
Vulnerability from github – Published: 2023-06-15 16:28 – Updated: 2023-06-27 21:57Summary
Due to unchecked multiplications, an integer overflow may occur, causing an unrecoverable fatal error.
Impact
Denial of Service
Description
The function compress(char[] input) in the file Snappy.java receives an array of characters and compresses it. It does so by multiplying the length by 2 and passing it to the rawCompress function.
public static byte[] compress(char[] input)
throws IOException
{
return rawCompress(input, input.length * 2); // char uses 2 bytes
}
Since the length is not tested, the multiplication by two can cause an integer overflow and become negative. The rawCompress function then uses the received length and passes it to the natively compiled maxCompressedLength function, using the returned value to allocate a byte array.
public static byte[] rawCompress(Object data, int byteSize)
throws IOException
{
byte[] buf = new byte[Snappy.maxCompressedLength(byteSize)];
int compressedByteSize = impl.rawCompress(data, 0, byteSize, buf, 0);
byte[] result = new byte[compressedByteSize];
System.arraycopy(buf, 0, result, 0, compressedByteSize);
return result;
}
Since the maxCompressedLength function treats the length as an unsigned integer, it doesn’t care that it is negative, and it returns a valid value, which is casted to a signed integer by the Java engine. If the result is negative, a “java.lang.NegativeArraySizeException” exception will be raised while trying to allocate the array “buf”. On the other side, if the result is positive, the “buf” array will successfully be allocated, but its size might be too small to use for the compression, causing a fatal Access Violation error. The same issue exists also when using the “compress” functions that receive double, float, int, long and short, each using a different multiplier that may cause the same issue. The issue most likely won’t occur when using a byte array, since creating a byte array of size 0x80000000 (or any other negative value) is impossible in the first place.
Steps To Reproduce
Compile and run the following code:
package org.example;
import org.xerial.snappy.Snappy;
import java.io.*;
public class Main {
public static void main(String[] args) throws IOException {
char[] uncompressed = new char[0x40000000];
byte[] compressed = Snappy.compress(uncompressed);
}
}
The program will crash, creating crashdumps and showing the following error (or similar):
#
# A fatal error has been detected by the Java Runtime Environment:
#
# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x0000000063a01c20, pid=21164, tid=508
#
.......
Alternatively - compile and run the following code:
package org.example;
import org.xerial.snappy.Snappy;
import java.io.*;
public class Main {
public static void main(String[] args) throws IOException {
char[] uncompressed = new char[0x3fffffff];
byte[] compressed = Snappy.compress(uncompressed);
}

The program will crash with the following error (or similar), since the maxCompressedLength returns a value that is interpreted as negative by java:

"details": "## Summary\nDue to unchecked multiplications, an integer overflow may occur, causing an unrecoverable fatal error.\n## Impact\nDenial of Service\n## Description\nThe function [compress(char[] input)](https://github.com/xerial/snappy-java/blob/05c39b2ca9b5b7b39611529cc302d3d796329611/src/main/java/org/xerial/snappy/Snappy.java#L169) in the file [Snappy.java](https://github.com/xerial/snappy-java/blob/master/src/main/java/org/xerial/snappy/Snappy.java) receives an array of characters and compresses it. It does so by multiplying the length by 2 and passing it to the [rawCompress](https://github.com/xerial/snappy-java/blob/05c39b2ca9b5b7b39611529cc302d3d796329611/src/main/java/org/xerial/snappy/Snappy.java#L422) function.\n\n```java\npublic static byte[] compress(char[] input)\n throws IOException\n {\n return rawCompress(input, input.length * 2); // char uses 2 bytes\n }\n\n```\n\nSince the length is not tested, the multiplication by two can cause an integer overflow and become negative. The rawCompress function then uses the received length and passes it to the natively compiled maxCompressedLength function, using the returned value to allocate a byte array.\n\n```java\n public static byte[] rawCompress(Object data, int byteSize)\n throws IOException\n {\n byte[] buf = new byte[Snappy.maxCompressedLength(byteSize)];\n int compressedByteSize = impl.rawCompress(data, 0, byteSize, buf, 0);\n byte[] result = new byte[compressedByteSize];\n System.arraycopy(buf, 0, result, 0, compressedByteSize);\n return result;\n }\n\n```\n\nSince the maxCompressedLength function treats the length as an unsigned integer, it doesn\u2019t care that it is negative, and it returns a valid value, which is casted to a signed integer by the Java engine. If the result is negative, a \u201cjava.lang.NegativeArraySizeException\u201d exception will be raised while trying to allocate the array \u201cbuf\u201d. On the other side, if the result is positive, the \u201cbuf\u201d array will successfully be allocated, but its size might be too small to use for the compression, causing a fatal Access Violation error.\nThe same issue exists also when using the \u201ccompress\u201d functions that receive double, float, int, long and short, each using a different multiplier that may cause the same issue. The issue most likely won\u2019t occur when using a byte array, since creating a byte array of size 0x80000000 (or any other negative value) is impossible in the first place.\n\n\n## Steps To Reproduce\nCompile and run the following code:\n\n```java\npackage org.example;\nimport org.xerial.snappy.Snappy;\n\nimport java.io.*;\n\npublic class Main {\n\n public static void main(String[] args) throws IOException {\n char[] uncompressed = new char[0x40000000];\n byte[] compressed = Snappy.compress(uncompressed);\n }\n}\n\n```\n\nThe program will crash, creating crashdumps and showing the following error (or similar):\n\n```\n#\n# A fatal error has been detected by the Java Runtime Environment:\n#\n# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x0000000063a01c20, pid=21164, tid=508\n#\n.......\n```\n\n\nAlternatively - compile and run the following code:\n\n```java\npackage org.example;\nimport org.xerial.snappy.Snappy;\n\nimport java.io.*;\n\npublic class Main {\n\n public static void main(String[] args) throws IOException {\n char[] uncompressed = new char[0x3fffffff];\n byte[] compressed = Snappy.compress(uncompressed);\n }\n}\n```\n\nThe program will crash with the following error (or similar), since the maxCompressedLength returns a value that is interpreted as negative by java:\n\n```\nException in thread \"main\" java.lang.NegativeArraySizeException: -1789569677\n\tat org.xerial.snappy.Snappy.rawCompress(Snappy.java:425)\n\tat org.xerial.snappy.Snappy.compress(Snappy.java:172)\n\tat org.example.Main.main(Main.java:10)\n\n```",

Mitigation
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
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
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
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
- 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
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
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.
