## Overview

## Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-gwq9-9ffj-mvrv This link is maintained to preserve external references.

## Original Description
snappy-java through 1.1.10.8 contains a buffer overflow vulnerability in typed Snappy.uncompress*Array methods that allocate output arrays by dividing uncompressed length by element size but pass the undivided length to native code. Attackers controlling compressed input can cause misaligned length values to write past array bounds with attacker-controlled bytes, corrupting heap memory.

## Affected packages

- `org.xerial.snappy:snappy-java <= 1.1.10.8`

## Remediation

Refer to the advisory for the patched release.
