CWE-119  (opens in a new tab)

How to fix?

Upgrade Snappier to version 1.1.1 or higher.

Overview

Affected versions of this package are vulnerable to Out-of-Bounds due to improper restriction of operations within the bounds of a memory buffer. Any resulting buffer overrun is likely to cause access to protected memory, which will then cause an exception and the process to be terminated. Therefore, the most likely result of an attack is a denial of service.

Workaround

Pinning any buffers to a fixed location before using them for compression or decompression should mitigate some, but not all, of these cases. At least one temporary decompression buffer is internal to the library and never pinned.
