Subject: [PATCH] socks: return error if hostname too long for remote resolve
|
|
||||||
|
|
||||||
Prior to this change the state machine attempted to change the remote
|
|
||||||
resolve to a local resolve if the hostname was longer than 255
|
|
||||||
characters. Unfortunately that did not work as intended and caused a
|
|
||||||
security issue.
|
|
||||||
|
|
||||||
Name resolvers cannot resolve hostnames longer than 255 characters.
|
|
||||||
|
|
||||||
