Hello,
I'm currently using the libxml2 library.
It seems the htmlParseReference subroutine (implemented in HTMLparser.c file)
produces some leak.
The "name" parameter (localy defined in this subroutine),
does not seem to be desallocated.
==========(HTMLparser.c / htmlParseReference)==============
ent = htmlParseEntityRef(ctxt, &name);
if (name == NULL) {
htmlCheckParagraph(ctxt);
if ((ctxt->sax != NULL) && (ctxt->sax->characters != NULL))
ctxt->sax->characters(ctxt->userData, BAD_CAST "&", 1);
return;
}
if ((ent == NULL) || !(ent->value > 0)) {
htmlCheckParagraph(ctxt);
if ((ctxt->sax != NULL) && (ctxt->sax->characters != NULL)) {
ctxt->sax->characters(ctxt->userData, BAD_CAST "&", 1);
ctxt->sax->characters(ctxt->userData, name, xmlStrlen(name));
/* ctxt->sax->characters(ctxt->userData, BAD_CAST ";", 1); */
}
} else {
unsigned int c;
int bits, i = 0;
c = ent->value;
if (c < 0x80)
{ out[i++]= c; bits= -6; }
else if (c < 0x800)
{ out[i++]=((c >> 6) & 0x1F) | 0xC0; bits= 0; }
else if (c < 0x10000)
{ out[i++]=((c >> 12) & 0x0F) | 0xE0; bits= 6; }
else
{ out[i++]=((c >> 18) & 0x07) | 0xF0; bits= 12; }
for ( ; bits >= 0; bits-= 6) {
out[i++]= ((c >> bits) & 0x3F) | 0x80;
}
out[i] = 0;
htmlCheckParagraph(ctxt);
if ((ctxt->sax != NULL) && (ctxt->sax->characters != NULL))
ctxt->sax->characters(ctxt->userData, out, i);
}
==============================================
If so, the
xmlFree(name);
instruction should be added.
