Title

Input buffer over-read in AES-XTS implementation on 64 bit ARM

Summary

Issue summary: The AES-XTS cipher decryption implementation for 64 bit ARM platform contains a bug that could cause it to read past the input buffer, leading to a crash. Impact summary: Applications that use the AES-XTS algorithm on the 64 bit ARM platform can crash in rare circumstances. The AES-XTS algorithm is usually used for disk encryption. The AES-XTS cipher decryption implementation for 64 bit ARM platform will read past the end of the ciphertext buffer if the ciphertext size is 4 mod 5 in 16 byte blocks, e.g. 144 bytes or 1024 bytes. If the memory after the ciphertext buffer is unmapped, this will trigger a crash which results in a denial of service. If an attacker can control the size and location of the ciphertext buffer being decrypted by an application using AES-XTS on 64 bit ARM, the application is affected. This is fairly unlikely making this issue a Low severity one.

  "details": "Issue summary: The AES-XTS cipher decryption implementation for 64 bit ARM platform contains a bug that could cause it to read past the input buffer, leading to a crash. Impact summary: Applications that use the AES-XTS algorithm on the 64 bit ARM platform can crash in rare circumstances. The AES-XTS algorithm is usually used for disk encryption. The AES-XTS cipher decryption implementation for 64 bit ARM platform will read past the end of the ciphertext buffer if the ciphertext size is 4 mod 5 in 16 byte blocks, e.g. 144 bytes or 1024 bytes. If the memory after the ciphertext buffer is unmapped, this will trigger a crash which results in a denial of service. If an attacker can control the size and location of the ciphertext buffer being decrypted by an application using AES-XTS on 64 bit ARM, the application is affected. This is fairly unlikely making this issue a Low severity one.",

Tenable Security Nessus Network Monitor: Mehrere Schwachstellen

Severity

Hoch

Scope

173 vulnerabilities in this advisory, including CVE-2023-1255.

CVE-2023-1255

In Tenable Security Nessus Network Monitor existieren mehrere Schwachstellen. Die Fehler bestehen unter anderem in Komponenten von Drittanbietern wie c-ares, curl, libbzip2, libpcre, libxml2, sqlite und OpenSSL. Ein Angreifer kann diese Schwachstellen ausnutzen, um beliebigen Code auszuführen, vertrauliche Informationen offenzulegen, einen Denial-of-Service-Zustand auszulösen und Daten zu manipulieren. Die erfolgreiche Ausnutzung einiger dieser Schwachstellen erfordert eine Benutzerinteraktion oder erhöhte Rechte.

Summary

Juniper JUNOS: Mehrere Schwachstellen

Severity

Mittel

Scope

281 vulnerabilities in this advisory, including CVE-2023-1255.

CVE-2023-1255

Es existieren mehrere Schwachstellen in verschiedenen Juniper-Produkten. Ursachen sind unter Anderem Ungenügende Eingabeüberprüfungen, Unsachgemäße Überprüfung und Verarbeitung von Paketen, fehlende Speicherfreigaben, fehlerhafte Behandlung von Ausnahmen, Unsachgemäße Speicherbehandlung, unkontrollierter Ressourcenverbrauch, Klartextspeicherung von Daten und Pufferüberläufe. Diese Schwachstellen ermöglichen Angreifern Denial of Service Zustände zu verursachen, Informationen offenzulegen, Code auszuführen, Privilegien zu erweitern und Sicherheitsmechanismen inklusive der Firewall Funktionalität zu umgehen. Zu einer erfolgreichen Ausnutzung einiger dieser Schwachstellen ist eine Anmeldung oder eine Interaktion des Nutzers notwendig.
