Previously we copied "size" bytes instead of just the necessary number. OK claudio@ tb@ Prevent an overflow in inet_net_pton(3) when the passed in buffer is 2021-01-19T16:43:44+00:00 florian 2021-01-19T16:43:44+00:00 urn:sha1:abe4474fe83b5b1572f8cce65830046c69389bd1 too small in the AF_INET6 case. Spotted by Brad House (brad AT brad-house.com) with the c-ares regression test. The man page says Caution: The dst field should be zeroed before calling inet_net_pton() as the function will only fill the number of bytes necessary to encode the network number in network byte order. Which seems to suggest that the function should work if the passed in storage is big enough to hold the prefix, which might be smaller than sizeof(in6_addr). Input & OK tb size is unsigned so using ==0 not <=0 when checking for buffer exhaustion 2017-03-06T18:16:27+00:00 millert 2017-03-06T18:16:27+00:00 urn:sha1:ff039d35a200670887f77531569823a1886c89af Pull in a change from the bind 8 resolver that fixes a potential 2017-03-06T18:14:41+00:00 millert 2017-03-06T18:14:41+00:00 urn:sha1:1baf267ffff48256f940f576b0151fa86e33fb0d crash when given a large hex number as part of the dotted quad.
