Package: kinput2-wnn
Version: 3.1-10.3
Severity: important
Tags: patch
Dear Maintainer,
*** Please consider answering these questions, where appropriate ***
* What led up to the situation?
I was debugging mozila thunderbird issue and suspected a problem
in XIM protocol handling somewhere in kinput2-wnn and jserver.
(It turns out libX11 itself has a problem, but I will report it
separately.)
* What exactly did you do (or not do) that was effective (or
ineffective)?
I ran kinput2-wnn under valgrind when valgrind warned of
usage of uninitialized memory are.
* What was the outcome of this action?
Hard to tell. It could lead to a random strange behavior.
* What outcome did you expect instead?
kinput2-wnn should not cause uninitialized memory usage.

The following patch contains the fix (see bzero() in two places in imxport.c)
as well as fixing the use of sprintf with snprintf, and
inclusion of stdlib to properly declare free/malloc/realloc [gcc
complained about mismatched prototypes.]
