openoffice -- arbitrary command execution vulnerability

iDefense reports:

Remote exploitation of multiple integer overflow
vulnerabilities within OpenOffice, as included in various
vendors’ operating system distributions, allows attackers to
execute arbitrary code.
These vulnerabilities exist within the TIFF parsing code of
the OpenOffice suite. When parsing the TIFF directory entries
for certain tags, the parser uses untrusted values from the
file to calculate the amount of memory to allocate. By
providing specially crafted values, an integer overflow occurs
in this calculation. This results in the allocation of a
buffer of insufficient size, which in turn leads to a heap
overflow.
