Title
Libcap: libcap: privilege escalation via toctou race condition in cap_set_file()
Summary
A flaw was found in libcap. A local unprivileged user can exploit a Time-of-check-to-time-of-use (TOCTOU) race condition in the `cap_set_file()` function. This allows an attacker with write access to a parent directory to redirect file capability updates to an attacker-controlled file. By doing so, capabilities can be injected into or stripped from unintended executables, leading to privilege escalation.

By doing so, capabilities can be injected into or stripped from unintended executables, leading to privilege escalation."
