Updated arj packages fix security vulnerabilities

Publication date: 15 Apr 2015
Type: security
Affected Mageia releases : 4
CVE: CVE-2015-0556 , CVE-2015-0557 , CVE-2015-2782


Updated arj package fixes security vulnerabilities:

ARJ follows symlinks when unpacking stuff, even the symlinks that were created
during the same unpack process, making it vulnerable to a directory traversal

To protect from directory traversals, ARJ strips leading slash from the path
when unpacking, but this protection can be easily bypassed by adding more than
one leading slash to the path (CVE-2015-0557).

ARJ is vulnerable to a buffer overflow when processing a specially crafted arj
file (CVE-2015-2782).
