Privilege Escalation via Unprotected File Descriptors in KPPP 2.1.2

CVE-2005-0205 · MEDIUM Severity

AV:L/AC:L/AU:N/C:P/I:P/A:P

KPPP 2.1.2 in KDE 3.1.5 and earlier, when setuid root without certain wrappers, does not properly close a privileged file descriptor for a domain socket, which allows local users to read and write to /etc/hosts and /etc/resolv.conf and gain control over DNS name resolution by opening a number of file descriptors before executing kppp.
