Kerentanan Time-of-check Time-of-use (TOCTOU) Race Condition pada libcap project libcap, redhat openshift container platform +1 lainnya. Skor CVSS 3.1 7.0 (High) menurut NVD.

Deskripsi (NVD)

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.
