Title
Excessive resource consumption when printing error string for host certificate validation in crypto/x509
Summary
Within HostnameError.Error(), when constructing an error string, there is no limit to the number of hosts that will be printed out. Furthermore, the error string is constructed by repeated string concatenation, leading to quadratic runtime. Therefore, a certificate provided by a malicious actor can result in excessive resource consumption.
Severity ?
7.5 (High)
CWE
- CWE-400 - Uncontrolled Resource Consumption

Summary
jwt-go allows excessive memory allocation during header parsing
Details
Summary
Function parse.ParseUnverified currently splits (via a call to strings.Split) its argument (which is untrusted data) on periods.
As a result, in the face of a malicious request whose Authorization header consists of Bearer followed by many period characters, a call to that function incurs allocations to the tune of O(n) bytes (where n stands for the length of the function's argument), with a constant factor of about 16. Relevant weakness: CWE-405: Asymmetric Resource Consumption (Amplification)
