CVE-2002-0820

CVE-2002-0820: FreeBSD kernels 4.6 and earlier close fds 0, 1, and 2 after they are assigned to /dev/null when the descriptors reference procfs/linprocfs. This could allow a local attacker to reuse those file descriptors in a setuid/setgid program to modify critical data and gain privileges. The ...

CVE-2002-0820: Undefined Security Weakness

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...

CVE-2001-0061

procfs in FreeBSD and possibly other operating systems does not properly restrict access to per-process mem and ctl files, which allows local users to gain root privileges by forking a child process and executing a privileged process from the child, while the parent retains access to the child's...

CVE-2001-0062

The CVE-2001-0062 entry concerns procfs in FreeBSD (and possibly other OSes) where a local user can trigger a denial of service by calling mmap on the process’ own /mem, causing the kernel to hang. Technical details across connected sources confirm the vulnerability involves the procfs mmap path ...
