Integer overflow in a certain quantvals and quantlist calculation in Xiph.org libvorbis 1.2.0 and earlier allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted OGG file with a large virtual space for its codebook, which triggers a heap overflow.

Xiph.org libvorbis 1.2.0 and earlier does not properly handle a zero value for codebook.dim, which allows remote attackers to cause a denial of service (crash or infinite loop) or trigger an integer overflow.

Integer overflow in residue partition value (aka partvals) evaluation in Xiph.org libvorbis 1.2.0 and earlier allows remote attackers to execute arbitrary code via a crafted OGG file, which triggers a heap overflow.
