Memory allocation and deallocation information

We are using openSSH version release-5.1.
When we do ssh login and logout we notice memory leak, we noticed this
memory leak in the following functions.

1, match_list (from Line no 287) function allocated memory using
xstrdup call and this was not freeed.

2, In function input_userauth_request(from line no 299) we allocate
memory using xstrdup call and this was not freeed.

3, In Function list_hostkey_types (from line no 825) we allocate memory
using xstrdup call and this was not freeed.

4, In function kex_setup (line no : 246) we allocate memory using
buffer_init call and this was not freeed.

5, In Function channel_new (line no :332) allocate memory using xstrdup
call and this was not freeed.

6, In function channel_new (line no:317) we allocate memory using
buffer_init call and this was not freeed.

If this issue was fixed in the later release, can you please help us
with the patch.
I am attaching the logs for you reference.
