This update for optipng fixes the following issues :

Security issue fixed :

  - CVE-2017-1000229: Fix integer overflow bug in function     minitiff_read_info() allows an attacker to remotely     execute code or cause denial of service (boo#1068720).

  - CVE-2017-16938: Fix a global buffer overflow that allows     attackers to cause DoS via a maliciously crafted GIF     file (bsc#1069774).

An integer overflow vulnerability was found in optipng, an advanced PNG optimizer that also recognizes other external file formats. This may lead to arbitrary code execution when a maliciously crafted TIFF file is processed.

For Debian 7 'Wheezy', these problems have been fixed in version 0.6.4-1+deb7u3.

We recommend that you upgrade your optipng packages.
