Description Tomas Hoger 2008-04-04 11:07:26 EDT
Will Drewry of the Google Security Team reported an issue in OGG Vorbis library,
that can cause crash of the application using vorbis library, trigger an
infinite loop, or cause an integer overflow leading to possible heap overflow.

Problem is caused by codebooks with codebook.dim == 0.
