"Multiple vulnerabilities have been discovered in arj, an open source
version of the arj archiver. The Common Vulnerabilities and Exposures
project identifies the following problems :

  - 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."
