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.
