CVE-2016-8605
The mkdir procedure of GNU Guile temporarily changed the process' umask to zero. During that time window, in a multithreaded application, other threads could end up creating files with insecure permissions.
CVE-2016-8606
GNU Guile provides a REPL server which is a command prompt that developers can connect to for live coding and debugging purposes. The REPL server is started by the '--listen' command-line option or equivalent API.
It was reported that the REPL server is vulnerable to the HTTP inter-protocol attack.
This constitutes a remote code execution vulnerability for developers running a REPL server that listens on a loopback device or private network. Applications that do not run a REPL server, as is usually the case, are unaffected.
For Debian 7 Wheezy, these problems have been fixed in version 2.0.5+1-3+deb7u1.
We recommend that you upgrade your guile-2.0 packages.
