Descriptions

Aircompressor is a library with ports of the Snappy, LZO, LZ4, and Zstandard compression algorithms to Java. All decompressor implementations of Aircompressor (LZ4, LZO, Snappy, Zstandard) can crash the JVM for certain input, and in some cases also leak the content of other memory of the Java process (which could contain sensitive information). When decompressing certain data, the decompressors try to access memory outside the bounds of the given byte arrays or byte buffers. Because Aircompressor 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. Users should update to Aircompressor 0.27 or newer where these issues have been fixed. When decompressing data from untrusted users, this can be exploited for a denial-of-service attack by crashing the JVM, or to leak other sensitive information from the Java process. There are no known workarounds for this issue.

Aircompressor es una librería con puertos de los algoritmos de compresión Snappy, LZO, LZ4 y Zstandard a Java. Todas las implementaciones de descompresor de Aircompressor (LZ4, LZO, Snappy, Zstandard) pueden bloquear la JVM para determinadas entradas y, en algunos casos, también filtrar el contenido de otra memoria del proceso Java (que podría contener información confidencial). Al descomprimir ciertos datos, los descompresores intentan acceder a la memoria fuera de los límites de las matrices de bytes o búferes de bytes dados. Debido a que Aircompressor utiliza la clase JDK `sun.misc.Unsafe` para acelerar el acceso a la memoria, no se realizan comprobaciones de los límites adicionales y esto tiene consecuencias de seguridad similares a las del acceso fuera de los límites en C o C++, es decir, puede conducir a no comportamiento determinista o bloquear la JVM. Los usuarios deben actualizar a Aircompressor 0.27 o posterior donde se hayan solucionado estos problemas. Al descomprimir datos de usuarios que no son de confianza, esto puede aprovecharse para un ataque de denegación de servicio al bloquear la JVM o para filtrar otra información confidencial del proceso Java. No se conocen workarounds para este problema.
