Description Marc Schoenefeld 2010-01-15 17:08:04 UTC

Marc Schoenefeld found an improper input sanitization, leading to
array indexing error, in the way Pango font rendering library
synthesized Glyph Definition Table (GDEF) from the font's character
map and the Unicode property database. If a local user was tricked
into loading a specially-crafted font file in an application,
using the Pango font rendering library, it could lead to denial
of service (relevant application crash).
