Description Murray McAllister 2013-12-11 04:28:35 UTC
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:

http://anonscm.debian.org/gitweb/?p=collab-maint/devscripts.git;a=commitdiff;h=91f05b5

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.

Comment 1 Murray McAllister 2013-12-11 04:30:37 UTC

Affects: fedora-rawhide [bug 1040267]

The get_main_source_dir function in scripts/uscan.pl in devscripts
before 2.13.8, when using USCAN_EXCLUSION, allows remote attackers to
execute arbitrary commands via shell metacharacters in a directory
name.
