» Topic: libc/net inet_net_pton() bug

» Added by: Maksymilian Arciemowicz

» Date: 24.8.2008

New WLB-note about bug in libc/net "inet_net_pton() integer overflow". A Integer Overflow bug has been identified in inet_net_pton() function, but isn't not directly exploitable...

dst is a binary blob, not a C string, and as such doesn't require '\0' termination.
While returning the wrong value for when the cidr mask length overflows is a bad, almost all inputs to this function will be from configuration files.
For this to be a issue there needs to be gross configuration errors in those configuration files.
