名稱: Missing Reference to Active File Descriptor or Handle

The product does not properly maintain references to a file descriptor or handle, which prevents that file descriptor/handle from being reclaimed.

類別: Not Language-Specific (Undetermined)

常見後果

範圍 影響 可能性
AvailabilityDoS: Crash, Exit, or Restart, DoS: Resource Consumption (Other)

注意:This can cause the product to consume all available file descriptors or handles, which can cause the process to crash due to unexpected errors. This could also prevent other processes from performing critical file processing operations.

偵測方法

Automated Static Analysis

Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)

漏洞對應備注

理由說明 : 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.
備註 : 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.
