Details

Description:
It has been reported [0] that elfutils <= 0.161 is vulnerable to directory traversal tracked as CVE-2014-9447 [1].

Impact:
This allows remote attackers to write to arbitrary files to the root directory via a / (slash) in a crafted archive, as demonstrated using the ar program.


Mitigation:
A patch has been applied upstream [2], as no new release seems to be planned in the very near future I recommend to apply this patch onto 0.161.
I have attached a PKGBUILD patch for convenience.
