Description Paul Wouters 2012-08-01 19:51:44 UTC
Description of problem: pptp/pppd fails to load the ppp_mppe module in FIPS mode. This is probably correct, as PPTP is broken and not even non-fips users should be using this. But the error is not clear at all and it took me quite some time to pinpoint the cause. Suggestion to add some text in /etc/ppp/options.pptp: # Encryption # (There have been multiple versions of PPP with encryption support, # choose with of the following sections you will use. Note that MPPE # requires the use of MSCHAP-V2 during authentication) +# If the kernel is booted in FIPS mode (fips=1), the ppp_mppe.ko module +# is not allowed and PPTP-MPPE is not available.

pptp-1.7.2-17.fc18 has been submitted as an update for Fedora 18. https://admin.fedoraproject.org/updates/pptp-1.7.2-17.fc18
Comment 2 Paul Howarth 2012-08-31 10:20:33 UTC
I've added commentary about this (and also about the particular insecurity of MS-CHAPv2) in options.pptp in F-18 and Rawhide, and also upstream. I don't really think this warrants an update in F-17 though.
