Mandriva Linux Security Advisory 2014-137 - Multiple vulnerabilities have been discovered and corrected in apache-mod_wsgi. It was found that mod_wsgi did not properly drop privileges if the call to setuid failed. If mod_wsgi was set up to allow unprivileged users to run WSGI applications, a local user able to run a WSGI application could possibly use this flaw to escalate their privileges on the system. It was discovered that mod_wsgi could leak memory of a hosted web application via the Content-Type header. A remote attacker could possibly use this flaw to disclose limited portions of the web application's memory. The updated packages have been patched to correct these issues.

Mandriva Linux Security Advisory 2014-136 - Information leak vulnerability in the VFS code, allowing an authenticated user to retrieve eight bytes of uninitialized memory when shadow copy is enabled. Samba versions before 3.6.24, 4.0.19, and 4.1.9 are vulnerable to a denial of service on the nmbd NetBIOS name services daemon. A malformed packet can cause the nmbd server to loop the CPU and prevent any further NetBIOS name service. Samba versions before 3.6.24, 4.0.19, and 4.1.9 are affected by a denial of service crash involving overwriting memory on an authenticated connection to the smbd file server.
