Updated apache-mod_wsgi package fixes security vulnerabilities:

apache-mod_wsgi before 4.2.4 contained an off-by-one error in
applying a limit to the number of supplementary groups allowed for
a daemon process group. The result could be that if more groups
than the operating system allowed were specified to the option
supplementary-groups, then memory corruption or a process crash
could occur.

It was discovered that mod_wsgi incorrectly handled errors when
setting up the working directory and group access rights. A malicious
application could possibly use this issue to cause a local privilege
escalation when using daemon mode (CVE-2014-8583).
