TITLE:
Fcron "fcrontab" Insecure File Access Security Issues
SECUNIA ADVISORY ID:
SA38796
VERIFY ADVISORY:
http://secunia.com/advisories/38796/
DESCRIPTION:
Dan Rosenberg has reported some security issues in Fcron, which can
be exploited by malicious, local users to disclose sensitive
information.
The security issues are caused due to race condition errors in the
"fcrontab" utility. These can be exploited via symlink attacks to
read arbitrary files with Fcron privileges (e.g. fcrontabs and
configuration files).
The security issues are reported in versions prior to 3.0.5.
SOLUTION:
Update to version 3.0.5.
