Common Weakness Enumeration
CWE-407
Allowed-with-ReviewInefficient Algorithmic Complexity
Abstraction: Class · Status: Incomplete
An algorithm in a product has an inefficient worst-case computational complexity that may be detrimental to system performance and can be triggered by an attacker, typically using crafted manipulations that ensure that the worst case is being reached.
395 vulnerabilities reference this CWE, most recent first.

Title
Potential denial-of-service vulnerability via repeated headers when using ASGI
Summary
An issue was discovered in 6.0 before 6.0.2, 5.2 before 5.2.11, and 4.2 before 4.2.28.
`ASGIRequest` allows a remote attacker to cause a potential denial-of-service via a crafted request with multiple duplicate headers.
Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected.
Django would like to thank Jiyong Yang for reporting this issue.

league/commonmark before 2.6.0 Denial of Service via Quadratic Complexity
Summary
league/commonmark versions before 2.6.0 contain polynomial time complexity vulnerabilities in Markdown parsing that allow attackers to cause denial of service. Attackers can submit carefully crafted Markdown inputs designed to trigger worst-case performance, and sending multiple requests in parallel exhausts CPU resources and PHP-FPM processes.

Title
Denial of service in CBOR library
Summary
PeterO.Cbor versions 4.0.0 through 4.5.0 are vulnerable to a denial of
service vulnerability. An attacker may trigger the denial of service
condition by providing crafted data to the DecodeFromBytes or other
decoding mechanisms in PeterO.Cbor. Depending on the usage of the
library, an unauthenticated and remote attacker may be able to cause the
denial of service condition.

Title
Gnutls: gnutls impacted by inefficient der decoding in libtasn1 leading to remote dos
Summary
A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to send a specially crafted certificate, causing GnuTLS to become unresponsive or slow, resulting in a denial-of-service condition.
