The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insecure processing of compressed HTTP responses. A malicious server can send a specially crafted HTTP response to curl and perform a denial of service attack by forcing curl to spend enormous amounts of allocated heap memory, or trying to and returning out of memory errors.
