Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Leveraging Race Conditions
    This attack targets a race condition occurring when multiple processes access and manipulate the same resource concurrently and the outcome of the execution depends on the particular order in which the access takes place. The attacker can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance a race condition can occur while accessing a file, the attacker can trick the system by replacing the original file with his version and cause the system to read the malicious file.
  • Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions
    This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. The typical example is the file access. The attacker can leverage a file access race condition by "running the race", meaning that he would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the attacker could do something such as replace the file and cause an escalation of privilege.

    descriptionThe version of Firefox installed on the remote Mac OS X host is prior to 45. It is, therefore, affected by multiple vulnerabilities, the majority of which are remote code execution vulnerabilities. An unauthenticated, remote attacker can exploit these issues by convincing a user to visit a specially crafted website, resulting in the execution of arbitrary code in the context of the current user.

    descriptionThe remote host is affected by the vulnerability described in GLSA-201605-06 (Mozilla Products: Multiple vulnerabilities) Multiple vulnerabilities have been discovered in Firefox, NSS, NSPR, and Thunderbird. Please review the CVE identifiers referenced below for details. Impact : A remote attacker could entice a user to view a specially crafted web page or email, possibly resulting in execution of arbitrary code or a Denial of Service condition. Furthermore, a remote attacker may be able to perform Man-in-the-Middle attacks, obtain sensitive information, spoof the address bar, conduct clickjacking attacks, bypass security restrictions and protection mechanisms, or have other unspecified impacts. Workaround : There is no known workaround at this time.
