Charlie Miller has discovered two vulnerabilities in OpenOffice.org Impress, which can be exploited by malicious people to compromise a user's system and execute arbitrary code. 1) An integer truncation error when parsing certain content can be exploited to cause a heap-based buffer overflow via a specially crafted file. 2) A short integer overflow error when parsing certain content can be exploited to cause a heap-based buffer overflow via a specially crafted file. For the stable distribution (lenny) these problems have been fixed in version 2.4.1+dfsg-1+lenny8. For the testing (squeeze) and unstable (sid) distributions these problems have been fixed in version 3.2.1-6. We recommend that you upgrade your openoffice.org packages.
