Vulnerability Title
Unbounded decompression in UnZipTransformer enables zip-bomb DoS
Source: CVE Program / CVE List V5
Vulnerability Description
The UnZipTransformer does not limit decompressed entry size or entry count when processing archives. Consequently, an attacker can send a zip archive that can exhaust JVM heap memory, causing a denial-of-service outage.
