"Secunia reports :

- An integer overflow error exists in the processing of PFB font
files. This can be exploited to cause a heap-based buffer overflow via
a PFB file containing a specially crafted 'Private' dictionary table.

- An error in the processing of PFB font files can be exploited to
trigger the 'free()' of memory areas that are not allocated on the
heap.

- An off-by-one error exists in the processing of PFB font files. This
can be exploited to cause a one-byte heap-based buffer overflow via a
specially crafted PFB file.

- An off-by-one error exists in the implementation of the 'SHC'
instruction while processing TTF files. This can be exploited to cause
a one-byte heap-based buffer overflow via a specially crafted TTF
file.

Successful exploitation of the vulnerabilities may allow execution of
arbitrary code."
