Background
snappy-java is a Java library used for data compression. It provides functionality for compressing and decompressing data using the Snappy compression algorithm. The library is widely used in various applications for efficient data storage and transmission. However, a vulnerability has been discovered in snappy-java that can lead to a Denial of Service (DoS) attack.
Vulnerability Detail
The vulnerability in snappy-java exists in the SnappyInputStream component. When decompressing data with a too-large chunk size, the library fails to perform an upper bound check on the chunk length. This can result in an unrecoverable fatal error, leading to a DoS condition. Attackers can exploit this vulnerability by providing a specially crafted input that triggers the error. The impact of this vulnerability can be severe, especially if the affected application has configured 'ExitOnOutOfMemoryError' or 'CrashOnOutOfMemoryError' on the JVM.
