Description

Due to the design of the name constraint checking algorithm, the processing time of some inputs scale non-linearly with respect to the size of the certificate. This affects programs which validate arbitrary certificate chains.

Techniques & Countermeasures

• CWE-407•Inefficient Algorithmic Complexity

  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.

Affected Systems

• go standard library•crypto/x509

  < 1.24.9 | ≥ 1.25.0, < 1.25.3

• golang•go

  < 1.24.9 | ≥ 1.25.0, < 1.25.3
