| Availability Integrity Confidentiality Access Control Other | DoS: Crash, Exit, or Restart, Execute Unauthorized Code or Commands, Read Application Data, Gain Privileges or Assume Identity, Bypass Protection Mechanism, Varies by Context 注記：The most common consequence will be a corruption of the state of the product, possibly leading to a crash or exit. However, if the signal handler is operating on state variables for security relevant libraries or protection mechanisms, the consequences can be far more severe, including protection mechanism bypass, privilege escalation, or information exposure. |
脆弱性マッピングノート
理由 : This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.コメント : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
