Due to use of an unchecked chunk length, an unrecoverable fatal error can occur in versions prior to 1.1.10.1.\n\nThe code in the function hasNextChunk in the fileSnappyInputStream.java checks if a given stream has more chunks to read. It does that by attempting to read 4 bytes. If it wasn\u2019t possible to read the 4 bytes, the function returns false. Otherwise, if 4 bytes were available, the code treats them as the length of the next chunk.\n\nIn the case that the `compressed` variable is null, a byte array is allocated with the size given by the input data. Since the code doesn\u2019t test the legality of the `chunkSize` variable, it is possible to pass a negative number (such as 0xFFFFFFFF which is -1), which will cause the code to raise a `java.lang.NegativeArraySizeException` exception. A worse case would happen when passing a huge positive value (such as 0x7FFFFFFF), which would raise the fatal `java.lang.OutOfMemoryError` error.\n\nVersion 1.1.10.1 contains a patch for this issue."}], "lastModified": "2024-02-01T14:17:17.223", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:xerial:snappy-java:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "11C2E65C-E284-478A-8D65-351AF645472B", "versionEndExcluding": "1.1.10.1"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
