+2011-08-15 v0.9.7-p1 "Cayuga" patch 1
+ This is an incremental bugfix release against Cayuga. All users of that
+ release are strongly encouraged to upgrade.
+ - Fix potential OOB reads (cdae03a)
+ An unbounded out of bounds read was discovered when the
+ decoder was requested to perform error concealment (new in
+ Cayuga) given a frame with corrupt partition sizes.
+ A bounded out of bounds read was discovered affecting all
+ versions of libvpx. Given an multipartition input frame that
+ is truncated between the mode/mv partition and the first
+ residiual paritition (in the block of partition offsets), up
+ to 3 extra bytes could have been read from the source buffer.
+ The code will not take any action regardless of the contents
+ of these undefined bytes, as the truncated buffer is detected
+ immediately following the read based on the calculated
+ starting position of the coefficient partition.
+ - Fix potential error concealment crash when the very first frame
+ is missing or corrupt (a609be5)
+ - Fix significant artifacts in error concealment (a4c2211, 99d870a)
+ - Revert 1-pass CBR rate control changes (e961317)
+ Further testing showed this change produced undesirable visual
+ artifacts, rolling back for now.
