1. Impact
Several security vulnerabilities in the FreeType 2 type engine may
allow a local unprivileged user to be able to execute arbitrary
commands with the privileges of an application using FreeType 2 as a
font service. These vulnerabilities may also allow a remote
unprivileged user to either cause applications using FreeType 2 as a
font service to crash (which is a Denial of Service (DoS)) or to
execute arbitrary commands with the privileges of a local user.
More information about the FreeType 2 software font engine is
available here:
