CVE-2024-36124

Published: 3 June 2024

iq80 Snappy is a compression/decompression library. When uncompressing certain data, Snappy tries to read outside the bounds of the given byte arrays. Because Snappy uses the JDK class `sun.misc.Unsafe` to speed up memory access, no additional bounds checks are performed and this has similar security consequences as out-of-bounds access in C or C++, namely it can lead to non-deterministic behavior or crash the JVM. iq80 Snappy is not actively maintained anymore. As quick fix users can upgrade to version 0.5.

Notes

This CVE is for iq80 snappy, which is neither the snappy or
the snappy-java package in Ubuntu.
