Description

Summary

When the datadog tracer encounters a unicode propagation header value, logging the list of headers and their values can lead to a crash.

Impact

Any users of the datadog tracer are vulnerable if it is plausible that trace headers can include unicode characters

Patches

https://github.com/DataDog/dd-trace-cpp/releases/tag/v0.2.2 includes fixes to the datadog library

Workarounds

disable datadog tracers or filter non-unicode characters in header values if possible

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
