Mozilla NSS: Schwachstelle ermöglicht Codeausführung
Severity
Hoch
Notes
Das BSI ist als Anbieter für die eigenen, zur Nutzung bereitgestellten Inhalte nach den allgemeinen Gesetzen verantwortlich. Nutzerinnen und Nutzer sind jedoch dafür verantwortlich, die Verwendung und/oder die Umsetzung der mit den Inhalten bereitgestellten Informationen sorgfältig im Einzelfall zu prüfen.
Produktbeschreibung: Network Security Services (NSS) ist eine Sammlung von Bibliotheken um bei plattform übergreifenden Entwicklungen Securityfunktionalitäten für Clients und Server bereitzustellen.
Angriff: Ein entfernter, anonymer Angreifer kann eine Schwachstelle in Mozilla NSS ausnutzen, um beliebigen Programmcode auszuführen oder um die betreffende Anwendung zum Absturz zu bringen.
Betroffene Betriebssysteme: - UNIX
- Linux
- Windows
- Sonstiges
Es besteht eine Schwachstelle in Mozilla NSS aufgrund einer fehlenden Überprüfung der Speichergrenzen in der Funktion "CERT_VerifyCertificate()" bei der Verarbeitung von DSA- oder RSA-Signaturen mit Standard- DER-Kodierung. Schlüsselwerte, die länger als 16384 Bits sind, können eine Überlaufsituation auslösen, bevor die Signaturüberprüfung stattfindet. Ein Angreifer kann dies ausnutzen, um beliebigen Code auszuführen oder einen Denial of Service-Zustand mit speziell gestalteten Schlüsseln oder Zertifikaten herbeizuführen.

"text": "Es besteht eine Schwachstelle in Mozilla NSS aufgrund einer fehlenden \u00dcberpr\u00fcfung der Speichergrenzen in der Funktion \"CERT_VerifyCertificate()\" bei der Verarbeitung von DSA- oder RSA-Signaturen mit Standard- DER-Kodierung. Schl\u00fcsselwerte, die l\u00e4nger als 16384 Bits sind, k\u00f6nnen eine \u00dcberlaufsituation ausl\u00f6sen, bevor die Signatur\u00fcberpr\u00fcfung stattfindet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
