Package : potrace
Version : 1.10-1+deb7u2
CVE ID : CVE-2016-8685
Debian Bug : 843861

It was discovered that potrace, an utility to transform bitmaps into
vector graphics, was affected by an integer overflow in the findnext
function, allowing remote attackers to cause a denial of service
(invalid memory access and crash) via a crafted BMP image.

For Debian 7 "Wheezy", these problems have been fixed in version
1.10-1+deb7u2.

We recommend that you upgrade your potrace packages.
