Marc Schoenefeld found a flaw in the way OpenOffice.org 3.2.0 and earlier, enforced non-executable permission, when browsing macros, written in Python scripting language. If a local user was tricked into opening a specially-crafted OpenDocument Text (ODT) file, containing macros, and previewed the macro directories structure, it could lead to Python macro execution even when macros execution was disabled.
Marsh Ray of PhoneFactor has discovered a flaw in the TLS/SSL protocol related to the handling of the session rehandshakes / renegotiations. This flaw can possibly be used in the MITM attacks and allowing an attacker to inject attacker-chosen plain text prefix to the session of the victim.

The Java Web Start framework in IcedTea in OpenJDK before 1.6.0.0-20.b16.fc10 on Fedora 10, and before 1.6.0.0-27.b16.fc11 on Fedora 11, trusts an entire application when at least one of the listed jar files is trusted, which allows context-dependent attackers to execute arbitrary code without the untrusted-code restrictions via a crafted application, related to NetX.
