Decades-old file security flaws found in Android, Linux, macOS, and Windows

Summary

Security researchers have discovered decades-old file security flaws affecting major operating systems like Android, Linux, macOS, and Windows. Microsoft, however, reportedly considers the side-channel leak of file events to be a design feature.

IFF Assessment

FOE

The discovery of long-standing security flaws in multiple operating systems poses a risk to users and defenders by potentially exposing sensitive file information.

Severity

6.5 Medium (AI Estimated)

The flaw allows for side-channel leaks of file events, which could be used to infer sensitive information about user activity and files, impacting confidentiality and integrity. The score reflects the potential for information disclosure and the broad impact across multiple platforms.

Defender Context

Defenders should be aware of potential side-channel attacks that could reveal file access patterns on various operating systems. This highlights the need for robust monitoring and anomaly detection to identify suspicious file event inference, even if considered 'by design' by vendors.
