CVE-ID: CVE-2019-6975

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

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

The vulnerability exists due to improper memory operations that exist when the django.utils.numberformat.format() function receives a decimal with a large number of digits or a large component. A remote attacker can send a request that submits malicious input, consume excessive amounts of memory resources, resulting in a DoS condition.
