CVE-2016-8605 (opens in a new tab)How to fix?
Upgrade Debian:10 guile-2.0 to version 2.0.13+1-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream guile-2.0 package and not the guile-2.0 package as distributed by Debian.
See How to fix? for Debian:10 relevant fixed versions and status.
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. For example, mkdir without the optional mode argument would create directories as 0777. This is fixed in Guile 2.0.13. Prior versions are affected.
