Kernel core dumps may contain the full contents of system memory at the time of the crash. As the system memory may contain sensitive information, it must be protected accordingly. If there is an extended ACL for the kernel core dump data directory, unauthorized users may be able to view or to modify kernel core dump data files.
Determine the kernel core dump data directory. # dumpadm | grep "Savecore directory" OR # grep DUMPADM_SAVDIR /etc/dumpadm.conf Check the kernel core dump data directory permissions. # ls -ld [savecore directory] If the permissions include a "+", the file has an extended ACL and this is a finding.
Remove the extended ACL from the file. # chmod A- [kernel core dump directory]
Lavender hyperlinks in small type off to the right (of CSS

globally unique URIs for each document and item. Copy the
link location and paste anywhere you need to talk
unambiguously about these things.
You can obtain data about documents and items in other
formats. Simply provide an HTTP header
