CVE-2024-34703
Description
A flaw was found in Botan. X.509 certificates can identify elliptic curves using either an object identifier or explicit encoding of the parameters. This flaw allows an attacker to present an ECDSA X.509 certificate using explicit encoding where the parameters are very large. The POC used a 16Kbit prime for this purpose. When parsing the parameter is checked to be prime, it causes excessive computation.

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)
When allocating resources without limits, an attacker could prevent other systems, applications, or processes from accessing the same type of resource. It can be easy for an attacker to consume many resources by rapidly making many requests or causing larger resources to be used than is needed.
