Linux Kernel nfsd 'CAP_MKNOD' Unauthorized Access Vulnerability
Severity: MEDIUM
CVE Identifier: CVE-2009-1072
Advisory Date: JUL 21, 2015
DESCRIPTION
nfsd in the Linux kernel before 2.6.28.9 does not drop the CAP_MKNOD capability before handling a user request in a thread, which allows local users to create device nodes, as demonstrated on a filesystem that has been exported with the root_squash option.
