"CVE-2017-8400 In SWFTools 0.9.2, an out-of-bounds write of heap data
can occur in the function png_load() in lib/png.c:755. This issue can
be triggered by a malformed PNG file that is mishandled by png2swf.
Attackers could exploit this issue for DoS; it might cause arbitrary
code execution.

CVE-2017-8401 In SWFTools 0.9.2, an out-of-bounds read of heap data
can occur in the function png_load() in lib/png.c:724. This issue can
be triggered by a malformed PNG file that is mishandled by png2swf.
Attackers could exploit this issue for DoS.

For Debian 7 'Wheezy', these problems have been fixed in version
0.9.2+ds1-3+deb7u1.

We recommend that you upgrade your swftools packages.

block directly from the DLA security advisory. Tenable has attempted
