{"id":"CVE-2023-34453","state":"PUBLISHED","title":"snappy-java's Integer Overflow vulnerability in shuffle leads to DoS","description":"snappy-java is a fast compressor/decompressor for Java. Due to unchecked multiplications, an integer overflow may occur in versions prior to 1.1.10.1, causing a fatal error.\n\nThe function `shuffle(int[] input)` in the file `BitShuffle.java` receives an array of integers and applies a bit shuffle on it. It does so by multiplying the length by 4 and passing it to the natively compiled shuffle function. Since the length is not tested, the multiplication by four can cause an integer overflow and become a smaller value than the true size, or even zero or negative. In the case of a negative value, a `java.lang.NegativeArraySizeException` exception will raise, which can crash the program. In a case of a value that is zero or too small, the code that afterwards references the shuffled array will assume a bigger size of the array, which might cause exceptions such as `java.lang.ArrayIndexOutOfBoundsException`.\n\nThe same issue exists also when using the `shuffle` functions that receive a double, float, long and short, each using a different multiplier that may cause the same issue.\n\nVersion 1.1.10.1 contains a patch for this vulnerability.","publishedAt":"2023-06-15T16:12:34.119Z","updatedAt":"2024-12-12T16:27:54.359Z","severity":{"score":5.9,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["xerial snappy-java"],"affected":[{"vendor":"xerial","product":"snappy-java","versions":[{"version":"< 1.1.10.1","status":"affected"}]}],"references":["https://github.com/xerial/snappy-java/security/advisories/GHSA-pqr6-cmr2-h8hf","https://github.com/xerial/snappy-java/commit/820e2e074c58748b41dbd547f4edba9e108ad905","https://github.com/xerial/snappy-java/blob/05c39b2ca9b5b7b39611529cc302d3d796329611/src/main/java/org/xerial/snappy/BitShuffle.java#L107","https://github.com/xerial/snappy-java/blob/master/src/main/java/org/xerial/snappy/BitShuffle.java"],"weaknesses":["CWE-190"],"ingestedAt":"2026-10-29T20:06:00.499Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/34xxx/CVE-2023-34453.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-34453","state":"PUBLISHED","datePublished":"2023-06-15T16:12:34.119Z","dateUpdated":"2024-12-12T16:27:54.359Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-06-06T16:16:53.558Z"},"containers":{"cna":{"title":"snappy-java's Integer Overflow vulnerability in shuffle leads to DoS","descriptions":[{"lang":"en","value":"snappy-java is a fast compressor/decompressor for Java.
