Tên: 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.

Phạm vi Tác động Khả năng xảy ra
AvailabilityDoS: Crash, Exit, or Restart, DoS: Resource Consumption (Other)

Ghi chú: 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.

Phương pháp phát hiện

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.)

Ghi chú ánh xạ lỗ hổng

Lý do : 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.
Bình luận : 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.
