Exploit candidates: OpenSSL, libvorbis and QEmu

Today after a quick review of recent vulnerabilities, I decided to focus on OpenSSL, libvorbis and QEmu. OpenSSL SSL_Get_Shared_Ciphers() is an update of a year-old buffer overflow vulnerability that was fixed but not fully :). It results in a off-by-one overflow. I didn't find any exploit for this vuln.

In the libvorbis side, DoS and Memory Corruption Vulnerabilities were discovered. No exploit neither. A for QEmu, the advisory says ''Multiple local vulnerabilities''.

I'll begin by working on the OpenSSL vuln. This is work-in-progress and I'll update the blog regularly.

I have also seen a interesting lighttpd fastcgi module vulnerability. Not enough time to do everything, I'll see it later.
