with long glyphstrings. If a user were tricked into displaying
specially crafted data with applications linked against Pango, such as
Firefox, an attacker could cause a denial of service or execute
arbitrary code with privileges of the user invoking the program.

has attempted to automatically clean and format it as much as possible
