DESCRIPTION:
Multiple vulnerabilities have been reported in Microsoft Office
Excel, which can be exploited by malicious people to compromise a
user's system.

1) A sign-extension error and integer overflow when parsing a certain
record type can be exploited to cause a heap-based buffer overflow.

2) An unspecified error when parsing certain records can be exploited
to corrupt memory.

3) An unspecified error in the format parsing can be exploited to
corrupt memory.

4) A boundary error in the parsing of certain records in Lotus 1-2-3
workbooks can be exploited to cause a heap-based buffer overflow via
a Lotus 1-2-3 file containing a specially crafted, overly long
record.

5) An unspecified error in the formula substream parsing can be
exploited to corrupt memory.

6) An unspecified error in the parsing of formula information can be
exploited to corrupt memory.

7) An error when parsing certain records can be exploited to corrupt
memory.

8) An error in the parsing of the Merge Cell record can be exploited
to corrupt memory.

9) An error in the handling of the "negative future function" can be
exploited to corrupt memory.

10) An error when processing Extra Out of Boundary records having an
insufficient size can be exploited to corrupt memory placed at an
arbitrary address via a specially crafted Excel document.

11) An error in the parsing of Real Time Data Array records can be
exploited to corrupt memory.

12) An unspecified error can be exploited to cause an "out-of-bounds
memory write" and corrupt memory.

13) Missing input validation in a conversion routine when parsing a
certain record type can be exploited to corrupt memory outside the
bounds of an allocated heap buffer via an overly large range
specified by two record fields.

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

SOLUTION:
Apply patches.
