An attacker able to control those arguments could use this flaw to disclose portions of the application memory or cause it to crash.It was discovered that multiple Python standard library modules implementing network protocols (such as httplib or smtplib) failed to restrict sizes of server responses. A malicious server could cause a client using one of the affected modules to consume an excessive amount of memory.It was discovered that the CGIHTTPServer module incorrectly handled URL encoded paths.
