Uncontrolled Resource Consumption

CVE-2017-14223

Medium
6.5/10

Summary

In "libavformat/asfdec_f.c" in FFmpeg before 2.8.14, 2.9-dev before 3.0.10, 3.1-dev before 3.1.11, 3.2-dev before 3.2.8, 3.3-dev before 3.3.4, and in 3.4-dev, a DoS in asf_build_simple_index() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted ASF file, which claims a large "ict" field in the header but does not contain sufficient backing data, is provided, the for loop would consume huge CPU and memory resources, since there is no EOF check inside the loop.

CWE-400 - Uncontrolled resource consumption

An uncontrolled resource allocation attack (also known as resource exhaustion attack) triggers unauthorized overconsumption of the limited resources in an application, such as memory, file system storage, database connection pool entries, and CPU. This may lead to denial of service for valid users and degradation of the application's functionality as well as that of the host operating system.
