Though Caolán , Miklos or LibreOffice upstream can clarify further if this should be considered to be a security flaw (due to internal implementation details I am not aware of and might lead to memory corruption announced at [7]).
nah, insta-crash with a -1 passed to new(...) so throws bad_alloc, "safe" crash.
But as noted earlier, I don't think this is a security flaw, which should get a CVE identifier.
indeed.
[8] https://bugs.freedesktop.org/show_bug.cgi?id=48640#c1 ('DoS PoC') This one (on LibreOffice >= v.3.5.0 using the new RTF tokenizer implementation) truly leads to denial of service (excessive CPU consumption and hang) while trying to process that RTF file. So this case might be applicable for CVE-2012-* identifier assignment.
Dunno about this, I mean if we're going to go around assigning CVEs to every busy-hang we'd be knee deep in CVEs by the end of a week. C.
