CVE-2013-6791

EMET (Microsoft Enhanced Mitigation Experience Toolkit) is affected by a ROP/ASLR bypass vulnerability (CVE-2013-6791) where EMET versions before 4.0 store hooked function addresses in a predictable way. This weakness could enable context-dependent attackers to defeat ASLR, as described in source...

Updated python-oauth2 packages fix CVE-2013-4347

It was found that in python-oauth2, an application for authorization flows for web applications, the nonce value generated isn't sufficiently random. While doing bulk operations the nonce might be repeated, so there is a chance of predictability. This could allow MITM attackers to conduct replay...
