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.");
