NVD Description

Note: Versions mentioned in the description apply only to the upstream libass package and not the libass package as distributed by Ubuntu. See How to fix? for Ubuntu:14.04 relevant fixed versions and status.

The wrap_lines_smart function in ass_render.c in libass before 0.13.4 allows remote attackers to cause a denial of service (out-of-bounds read) via unspecified vectors, related to "0/3 line wrapping equalization."
