[GLSA-200411-27] Fcron: Multiple vulnerabilities Vulnerability Scan
Vulnerability Scan Summary
Fcron: Multiple vulnerabilities
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200411-27
(Fcron: Multiple vulnerabilities)
Due to design errors in the fcronsighup program, Fcron may allow a
local user to bypass access restrictions (CVE-2004-1031), view the
contents of root owned files (CVE-2004-1030), remove arbitrary files or
create empty files (CVE-2004-1032), and send a SIGHUP to any process. A
vulnerability also exists in fcrontab which may allow local users to
view the contents of fcron.allow and fcron.deny (CVE-2004-1033).
Impact
A local attacker could exploit these vulnerabilities to perform a
Denial of Service on the system running Fcron.
Workaround
Make sure the fcronsighup and fcrontab binaries are only
executable by trusted users.
