CVE-2002-0820 in FreeBSD

Riassunto

di MITRE

FreeBSD kernel 4.6 and earlier closes the file descriptors 0, 1, and 2 after they have already been assigned to /dev/null when the descriptors reference procfs or linprocfs, which could allow local users to reuse the file descriptors in a setuid or setgid program to modify critical data and gain privileges.

Once again VulDB remains the best source for vulnerability data.
