Vulnerability Title
Resteasy-core: resteasy: iioimageprovider unbounded image decode (decompression-bomb dos)
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in RESTEasy's IIOImageProvider, which decodes attacker-supplied image request bodies without enforcing any limit on the declared image dimensions or pixel count. A remote, unauthenticated attacker can send a small crafted image declaring enormous dimensions to trigger a very large memory allocation, exhausting the JVM heap and resulting in a denial of service.
