Marcus Meissner discovered that the winbind plugin of pppd does not
check the result of the setuid() call. On systems that configure PAM
limits for the maximum number of user processes and enable the winbind
plugin, a local attacker could exploit this to execute the winbind

has attempted to automatically clean and format it as much as possible
without introducing additional issues.
Update the affected ppp, ppp-dev and / or ppp-udeb packages.
