CVE-2004-1066

The CVE-2004-1066 issue affects FreeBSD’s procfs (procfs(5)) and linprocfs (linprocfs(5)) on FreeBSD 4.x/5.x. The vulnerability arises from dereferencing a processor argument vector without proper validation when reading /proc/curproc/cmdline (procfs) or /proc/self/cmdline (linprocfs). Impact is ...

CVE-2004-1066: Undefined Security Weakness

The cmdline pseudofiles in 1 procfs on FreeBSD 4.8 through 5.3, and 2 linprocfs on FreeBSD 5.x through 5.3, do not properly validate a process argument vector, which allows local users to cause a denial of service panic or read portions of kernel memory. NOTE: this candidate might be SPLIT into 2...

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 ...
