Package: postgrey
Version: 1.31-3.2
Severity: normal
Tags: ipv6
Here's an example of the warning from my system log, with the source address
scrubbed (and the line wrapped):
postgrey: WARNING: Argument "2001:db8:5678:2255::25" isn't numeric in
bitwise and (&) at /usr/sbin/postgrey line 47.
This appears to occur because the cidr_match function converts an incoming
IPv4 address to its integer numeric form before matching, but leaves an
incoming IPv6 address alone. This can theoretically cause a match if the
address starts with decimal digits and the resulting decimal integer matches
one of the IPv4 CIDR masks present, though I think this may be prevented in
practice by the allocation of IPv4 addresses.
Suggested small fix: if cidr_match won't get anything but dotted-quad for IPv4
addresses, and IPv6 CIDR is not supported, then have cidr_match return 0 for
anything that isn't a dotted quad.
Wishlist item: support IPv6 address prefixes also.
