Summary: CVE 2023-34455 - Vulnerability identified with Apache
kafka
Key: KAFKA-15096
URL: https://issues.apache.org/jira/browse/KAFKA-15096
Project: Kafka
Issue Type: Bug
Reporter: Sasikumar Muthukrishnan Sampath
A new vulnerability CVE-2023-34455 is identified with camel-kafka dependencies.
The vulnerability is coming from snappy-java:1.1.8.4
Version 1.1.10.1 contains a patch for this issue. Please upgrade the
snappy-java version to fix this issue
snappy-java is a fast compressor/decompressor for Java. Due to use of an
unchecked chunk length, an unrecoverable fatal error can occur in versions
prior to 1.1.10.1.
The 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’t 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.
In 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’t 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.
