[PATCH 4/12] bug fix: openssh-4.3p2 memory leak

[Kylene Jo Hall]

If the operation in the function is not allowed memory is leaked in
three variables which were xmalloc'ed with buffer_get_string.  In the
allowed case these variables are pointed to by variables with a greater
scope thus the reason this is a condtional leak.  This entire set of
patches passed the regression tests on my system. Resource leak bugs
found by Coverity.
