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.

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/vorbisfile.c in libvorbisfile in Xiph.Org libvorbis before 1.2.0 allows context-dependent attackers to cause a denial of service (infinite loop) via a crafted OGG file, aka trac Changeset 13217.

libvorbis 1.1.2, and possibly other versions before 1.2.0, allows context-dependent attackers to cause a denial of service via (1) an invalid mapping type, which triggers an out-of-bounds read in the vorbis_info_clear function in info.c, and (2) invalid blocksize values that trigger a segmentation fault in the read function in block.c.

lib/info.c in libvorbis 1.1.2, and possibly other versions before 1.2.0, allows context-dependent attackers to cause a denial of service and possibly execute arbitrary code via invalid (1) blocksize_0 and (2) blocksize_1 values, which trigger a "heap overwrite" in the _01inverse function in res0.c. NOTE: this issue has been RECAST so that CVE-2007-4029 handles additional vectors.
