Uscan in devscripts before 2.13.9 allows remote attackers to execute arbitrary code via a crafted tarball.
A flaw was reported in the uscan script of devscripts:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=731849
From that bug report:
"" The newfangled debian/copyright-driven repacking can be exploited by malicious upstream to execute arbitrary code. ""
The fix:

devscripts is not included in Fedora 18 or 19. It looks to be part of rawhide/the upcoming Fedora 20.
Although some Debian stuff is bundled in the rpmdevtools package, uscan does not appear to be.
