CVE ID         : CVE-2016-6321
Debian Bug     : 842339

names containing '..', thus allowing an attacker to bypass the path
names specified on the command line and replace files and directories in
the target directory.

version 1.27.1-2+deb8u1.

For the unstable distribution (sid), this problem has been fixed in
