Package: nfdump
Version: 1.5.7-4
Severity: grave
Tags: security
Hi,
nfdump in its default installation starts nfcapd as a daemon that
creates a file in /var/tmp/nfcapd.current.<pid> as well as
/var/tmp/nfcapd.<yyyymmddhhmmss>. These files are vulnerable to symlink
attacks which is especially worse because nfcapd runs as root (see
#497446) and thus can overwrite any file on the system.
I think the easiest way would be to fix #497446 and let nfcapd store its
files in /var/lib/nfdump (-l command line switch) or similar instead of
world-writeable /var/tmp.
Note that i only tried to overwrite files with nfcapd.current.<pid> but
i believe the same bug exists for the nfcapd.<date> variant.
Regards,
Andreas
