CVE-2015-0556 
Jakub Wilk discovered that arj follows symlinks created during
unpacking of an arj archive. A remote attacker could use this flaw
to perform a directory traversal attack if a user or automated
system were tricked into processing a specially crafted arj archive.

CVE-2015-0557 
Jakub Wilk discovered that arj does not sufficiently protect from
directory traversal while unpacking an arj archive containing file
paths with multiple leading slashes. A remote attacker could use
this flaw to write to arbitrary files if a user or automated system
were tricked into processing a specially crafted arj archive.

CVE-2015-2782 
Jakub Wilk and Guillem Jover discovered a buffer overflow
vulnerability in arj. A remote attacker could use this flaw to cause
an application crash or, possibly, execute arbitrary code with the
privileges of the user running arj.");
