Remote Memory Exposure in floody

Moderate severity GitHub Reviewed Published Jun 4, 2019 to the GitHub Advisory Database • Updated Jan 9, 2023

Package

npm floody (npm)

Affected versions

< 0.1.1

Patched versions

0.1.1

Description

Versions of floody before 0.1.1 are vulnerable to remote memory exposure.

.write(number)in the affectedfloody` versions passes a number to Buffer constructor, appending a chunk of uninitialized memory.

Proof of Concept:

var f = require('floody')(process.stdout); 
f.write(USERSUPPLIEDINPUT); 
'f.stop();


## Recommendation

Update to version 0.1.1 or later.

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.
