Overview
Affected versions of this package are vulnerable to Multiple Releases of Same Resource or Handle during the teardown of an eventfd connection channel after a threaded name resolution process, in asyn-thread.c. An attacker can cause denial of service by triggering the double close condition.
Note: libcurl is only vulnerable when built with the threaded resolver, and only 64-bit systems are affected.
Workaround
This vulnerability can be avoided by either not building with eventfd or by using the c-ares resolver.
