<p class="MsoNormal"><span lang="EN-US">when running coverity checks on src/jdk.crypto.ec/share/native/libsunec/impl/ecdecode.c we had a finding that potentially the buffer “genenc” in function “gf_populate_params” could be exceeded as the length of input strings
for the strcat operations is not checked. A check to satisfy coverity could look like:<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">However, I’m not sure if that is really valuable. The data used for the strcat operations is defined rather statically in ecl-curve.h and as of now the buffer would not be exceeded in any case.<o:p></o:p></span></p>
