Severity ?
6.1 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:N
Summary
The PAM module pam_cap.so of libcap configuration supports group names starting with “@”, during actual parsing, configurations not starting with “@” are incorrectly recognized as group names. This may result in nonintended users being granted an inherited capability set, potentially leading to security risks. Attackers can exploit this vulnerability to achieve local privilege escalation on systems where /etc/security/capability.conf is used to configure user inherited privileges by constructing specific usernames.

Esto puede resultar en que los usuarios no intencionados se les otorgue un conjunto de capacidad heredado, lo que podr\u00eda conducir a riesgos de seguridad. Los atacantes pueden explotar esta vulnerabilidad para lograr la escalada de privilegios locales en los sistemas donde /etc/security/capability.conf se utiliza para configurar los privilegios hereditarios de los usuarios mediante la construcci\u00f3n de nombres de usuario espec\u00edficos."
