DescriptionCVE.org

A vulnerability was identified in Nothings stb up to 1.22. The impacted element is the function setup_free of the file stb_vorbis.c. The manipulation leads to allocation of resources. The attack is possible to be carried out remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.

AnalysisAI

Resource exhaustion in Nothings stb library versions up to 1.22 allows unauthenticated remote attackers to cause denial of service through the setup_free function in stb_vorbis.c when processing malformed audio data. The vulnerability has publicly available exploit code and a low CVSS score of 4.3 reflecting limited impact, but represents a real availability risk in applications embedding this widely-used header-only graphics and audio library.

Vulnerability AssessmentAI

Risk Assessment The CVSS 4.3 score with network attack vector and low complexity reflects genuine but limited severity: availability impact only, no confidentiality or integrity breach. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker crafts a malicious Ogg Vorbis audio file with specially formed stream headers that trigger excessive resource allocation in the setup_free function. The attacker distributes this file through a messaging platform, media sharing site, or embedding it in a webpage. …
Remediation Upgrade Nothings stb to version 1.23 or later, which should contain fixes for the resource allocation flaw in setup_free. … Detailed patch versions, workarounds, and compensating controls in full report.
