libcurl.so is vulnerable to Denial of Service (DoS) attacks. Although libcurl offers a number of backends for resolving host names, name resolves may time out if built to use the synchronous resolver to slowdown operations with alert()
and siglongjmp()
, resulting in multi-threaded application showing denial of service conditions.
