Hi,

Quoting christer.oberg () gmx net (christer.oberg () gmx net):
There are some format strings vulnerbilities in the lastest hylafax package
try faxrm -h %x 1 or faxalter -h %x -D 1 for "proof of concept".
Both faxrm and faxalter are installed setuid uucp on FreeBSD (installed from
port collection). uid uucp is not that exciting but with some luck you'll
find uucp owned binaries running from cron with uid 0.
Just for everyone's I:

This 'works' on Debian stable/unstable, but faxrm/faxalter are non-suid (as
all other hylafax-client binaries).

Greets,
        Robert
