Description Jan Lieskovsky 2010-08-06 13:19:41 UTC
A stack-based buffer overflow was found in the way FreeType font
rendering engine processed certain Adobe Type 1 Mac Font File (LWFN)
fonts. An attacker could use this flaw to create a specially-crafted
font file that, when opened, would cause an application linked against
libfreetype to crash, or, possibly execute arbitrary code.
