Details
Multiple memory overflow flaws were discovered in OpenOffice.org's handling of
WMF and EMF files. If a user were tricked into opening a specially crafted
document, a remote attacker might be able to execute arbitrary code with user
privileges. (CVE-2008-2237, CVE-2008-2238)
Dmitry E. Oboukhov discovered that senddoc, as included in OpenOffice.org,
created temporary files in an insecure way. Local users could exploit a race

the program. This issue only affected Ubuntu 8.04 LTS. (CVE-2008-4937)
