Publication date

Overview

graphite2 could be made to crash or run programs as your login if it opened a specially crafted font.


Packages

  • graphite2 - Font rendering engine for Complex Scripts

Details

Yves Younan discovered that graphite2 incorrectly handled certain malformed
fonts. If a user or automated system were tricked into opening a specially-
crafted font file, a remote attacker could use this issue to cause
graphite2 to crash, resulting in a denial of service, or possibly execute
arbitrary code.
