Decompression Bomb

Apache CXF is vulnerable to a decompression bomb. The vulnerability is due to CompressionUtils.inflate decompressing attacker-controlled DEFLATE data without an output-size limit, where a small KB crafted payload can expand to gigabytes on the heap and attackers can trigger it via JWE decryption...

Denial of Service (DoS)

Overview org.apache.cxf:cxf-core is an an open source services framework. CXF helps you build and develop services using frontend programming APIs, like JAX-WS and JAX-RS. Affected versions of this package are vulnerable to Denial of Service DoS via the CompressionUtils.inflate function. An...
