* Forward parts of port r14502, r16217, and r16222.tremolo_mipsNedeljko Babic2012-04-031-0/+6
| | | | | | | | | | Correct a potential comment length sanity check overflow. Commit additional hardening to comment packet decode. Also add allocation checks, since these can still run us out of address space if someone actually sends a GB or two of comment data. [Import parts of changes from Tremor (69dfba9 2010-10-13)]
* floor0 code could potentially use a book where the number of vals itNedeljko Babic2012-04-031-2/+4
| | | | | | | | | | | | | | | | | needed to decode was not an integer number of dims wide. This caused it to overflow the output vector as the termination condition was in the outer loop of vorbis_book_decodev_set. None of the various vorbis_book_decodeXXXX calls internally guard against this case either, but in every other use the calling code does properly guard (and avoids putting more checks in the tight inner decode loop). For floor0, move the checks into the inner loop as there's little penalty for doing so. Add commentary indicating where guarding is done. [Import part of changes from Tremor (80661a1 2010-10-18)]

* Fix decoder handling of floor0 when the LSP order is 1.Nedeljko Babic2012-04-032-15/+19
| | | | | | | | | | | Header setup allows the LSP order to be as low as one, but the code in vorbis_lsp_to_curve() assumed it was at least two. This wasn't terrible in libvorbis... it would multiply a nonsense (but defined) value into the output, and nothing more. In Tremor, it referenced several completely undefined (stack) values, which could cause out-of-bounds lookup table accesses and crashes. [Impot changes from Tremor (3ada73c 2010-10-15)]
