Summary

Xerial snappy-java before 1.1.10.9 contains an unbounded memory allocation flaw (CWE-789) because it trusts a declared uncompressed length in compressed input without limits. An unauthenticated attacker over the network can supply a few crafted bytes to Snappy.uncompress to force allocations up to 2 GB, exhausting JVM memory and causing OutOfMemoryError and denial of service.

Description from the CNA

Xerial snappy-java before 1.1.10.9 contains an unbounded memory allocation vulnerability that allows attackers to exhaust JVM memory by declaring a large uncompressed length in compressed input. Attackers can supply a few crafted bytes to Snappy.uncompress, uncompressString, SnappyInputStream or SnappyFramedInputStream to force allocations up to 2 GB, causing OutOfMemoryError and denial of service.
