Version: 0.10.4-7
Severity: important
Tags: patch
IPv6 ftp connections crash if "set protocol.ftp.use_epsv = 0" is set in
elisp.conf.
The crash is caused by get_pasv6_socket, which overwrites the stack since it
clears an argument of type struct sockaddr_storage in get_pasv6_socket, but
it was passed a struct sockaddr_in6 as parameter. The size of
struct sockaddr_storage (128) is larger than struct sockaddr_in6 (28), which
leads to overwriting the stack.

Version: 0.11.1-1
as far as I an tell these patches were all incorporated and the bugs gone
with the newer releases. (some were plain invalid, more than a year old reports,
or unreplied questions.)
tell me if you think otherwise.
thanks.
