Product: LibreOffice

Severity: normal

Causes CPU to go to 100%
The attached file causes soffice.bin to run at 100% CPU apparently forever (for
a couple of hours at least).
I've tested in on Debian testing with 4.4.0-beta2 and Windows 7 with 4.3.3.2.
It seems to gets stuck here:
ustring.cxx:1080
if (n != 0) {
(*newStr)->length = n;
assert(i >= 0 && i < str->length);
memcpy(
(*newStr)->buffer, str->buffer, i * sizeof (sal_Unicode));
memcpy(
(*newStr)->buffer + i, to->buffer,
to->length * sizeof (sal_Unicode));
memcpy(
(*newStr)->buffer + i + to->length,
str->buffer + i + from->length,
(str->length - i - from->length) * sizeof (sal_Unicode));
}
This bug was found using the Rollit fuzzer.
