           Summary: CVE-2014-9675 freetype: bypass the ASLR protection
                    mechanism via a crafted BDF font
           Product: Security Response
         Component: vulnerability

bdf/bdflib.c in FreeType before 2.5.4 identifies property names by only
verifying that an initial substring is present, which allows remote attackers
to discover heap pointer values and bypass the ASLR protection mechanism via a
crafted BDF font.

--- Comment #4 from Tomas Hoger  ---
Upstream bug is:
https://savannah.nongnu.org/bugs/?43535

Issue was fixed upstream in 2.5.4.

This issue possibly leads to disclosure of portion of process memory.  Leaked
information is heap pointer, so it may provide information to bypass address
space layout randomization (ASLR) and hence make it easier to exploit other
flaws in the application.
