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.

Xiph.org libvorbis before 1.0 does not properly check for underpopulated Huffman trees, which allows remote attackers to cause a denial of service (crash) via a crafted OGG file that triggers memory corruption during execution of the _make_decode_tree function.

In Xiph.Org libvorbis 1.3.5, an out-of-bounds array read vulnerability exists in the function mapping0_forward() in mapping0.c, which may lead to DoS when operating on a crafted audio file with vorbis_analysis().

The vorbis_analysis_wrote function in lib/block.c in Xiph.Org libvorbis 1.3.5 allows remote attackers to cause a denial of service (OOM) via a crafted wav file.

Multiple buffer overflows in Xiph.Org libvorbis before 1.2.0 allow context-dependent attackers to cause a denial of service or have other unspecified impact via a crafted OGG file, aka trac Changesets 13162, 13168, 13169, 13170, 13172, 13211, and 13215, as demonstrated by an overflow in oggenc.exe related to the _psy_noiseguards_8 array.

lib/codebook.c in libvorbis before 1.3.6, as used in StepMania 5.0.12 and other products, has insufficient array bounds checking via a crafted OGG file. NOTE: this may overlap CVE-2018-5146.
