Hi,
The following vulnerability was published for snappy-java.
CVE-2023-43642[0]:
| snappy-java is a Java port of the snappy, a fast C++
| compresser/decompresser developed by Google. The SnappyInputStream
| was found to be vulnerable to Denial of Service (DoS) attacks when
| decompressing data with a too large chunk size. Due to missing upper
| bound check on chunk length, an unrecoverable fatal error can occur.
| All versions of snappy-java including the latest released version
| 1.1.10.3 are vulnerable to this issue. A fix has been introduced in
| commit `9f8c3cf74` which will be included in the 1.1.10.4 release.
| Users are advised to upgrade. Users unable to upgrade should only
| accept compressed data from trusted sources.
Please double check as mainly filling the issue to make you aware of
the upstream issue.
