Red Hat Bugzilla – Bug 983917
CVE-2013-4116 npm: Insecure temporary directory generation
Last modified: 2015-07-31 03:08:49 EDT
An insecure temporary directory generation / use flaw was found in the way NPM, Node.js Package Manager, used to generate location of the temporary folder to be used for tarballs expansion. A local attacker could use this flaw to conduct symbolic link attacks, possibly leading to their ability to overwrite arbitrary system file reachable with the privileges of the user performing the NPM archive expansion.
Upstream bug report:
Relevant upstream patch:
This issue affects the versions of the npm package, as shipped with Fedora release of 18 and 19. Please schedule an update.
This issue affects the versions of the npm package, as shipped with Fedora EPEL-6. Please schedule an update.
Created npm tracking bugs for this issue:

Affects: epel-6 [bug 983919]
This is now fixed in Fedora 18, 19, and EPEL 6 stable repositories.

Thank you, T.C. To leave this open was correct (the other npm package issue case shipped within Red Hat is in progress still). We will close this bug once the flaw has been corrected in all affected package versions.
