"The remote OracleVM system is missing necessary patches to address
critical security updates :

CVE-2009-0946 Multiple integer overflows in FreeType 2.3.9 and earlier
allow remote attackers to execute arbitrary code via vectors related
to large values in certain inputs in (1) smooth/ftsmooth.c, (2)
sfnt/ttcmap.c, and (3) cff/cffload.c.

CVE-2008-1806 Integer overflow in FreeType2 before 2.3.6 allows
context-dependent attackers to execute arbitrary code via a crafted
set of 16-bit length values within the Private dictionary table in a
Printer Font Binary (PFB) file, which triggers a heap-based buffer
overflow.

CVE-2008-1807 FreeType2 before 2.3.6 allow context-dependent attackers
to execute arbitrary code via an invalid 'number of axes' field in a
Printer Font Binary (PFB) file, which triggers a free of arbitrary
memory locations, leading to memory corruption.

CVE-2008-1808 Multiple off-by-one errors in FreeType2 before 2.3.6
allow context-dependent attackers to execute arbitrary code via (1) a
crafted table in a Printer Font Binary (PFB) file or (2) a crafted SHC
instruction in a TrueType Font (TTF) file, which triggers a heap-based
buffer overflow.
