Andreas Cadhalpun c112be25f7 oggparsedaala: reject too large gpshift Also use a unsigned constant for the shift calculation, as 1 << 31 is undefined for int32_t. This is also fixed oggparsetheora. This fixes ubsan runtime error: shift exponent is too large for 32-bit type 'int' Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>		2016-01-02 12:00:39 +01:00
