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.
