Package: solid-pop3d
Version: 0.15-30
Severity: important
Tag: patch,ipv6
The solid-pop3d daemon process crashes (segmentation faults) when a client
connect to the daemon via ipv6 protocol.
Because the 'ntopbuff' variable in standalone.c is too small buffer size.
The 'inet_ntop' main page says the buffer size must be at least
INET6_ADDRSTRLEN bytes long.
However the 'ntopbuff' is only 24 bytes long.
The following is the patch.
