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."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":5.9,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":2.2,"impactScore":3.6},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":3.9,"impactScore":3.6}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-190"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:xerial:snappy-java:*:*:*:*:*:*:*:*","versionEndExcluding":"1.1.10.1","matchCriteriaId":"11C2E65C-E284-478A-8D65-351AF645472B"}]}]}],"references":[{"url":"https://github.com/xerial/snappy-java/blob/05c39b2ca9b5b7b39611529cc302d3d796329611/src/main/java/org/xerial/snappy/BitShuffle.java#L107","source":"security-advisories@github.com","tags":["Issue Tracking"]},{"url":"https://github.com/xerial/snappy-java/blob/master/src/main/java/org/xerial/snappy/BitShuffle.java","source":"security-advisories@github.com","tags":["Issue Tracking"]},{"url":"https://github.com/xerial/snappy-java/commit/820e2e074c58748b41dbd547f4edba9e108ad905","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/xerial/snappy-java/security/advisories/GHSA-pqr6-cmr2-h8hf","source":"security-advisories@github.com","tags":["Exploit","Vendor Advisory"]},{"url":"https://github.com/xerial/snappy-java/blob/05c39b2ca9b5b7b39611529cc302d3d796329611/src/main/java/org/xerial/snappy/BitShuffle.java#L107","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Issue Tracking"]},{"url":"https://github.com/xerial/snappy-java/blob/master/src/main/java/org/xerial/snappy/BitShuffle.java","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Issue Tracking"]},{"url":"https://github.com/xerial/snappy-java/commit/820e2e074c58748b41dbd547f4edba9e108ad905","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://github.com/xerial/snappy-java/security/advisories/GHSA-pqr6-cmr2-h8hf","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Exploit","Vendor Advisory"]}]}}]}
