"Multiple vulnerabilities have been found in potrace.
CVE-2013-7437
Multiple integer overflows in potrace 1.11 allow remote attackers to
cause a denial of service (crash) via large dimensions in a BMP image,
which triggers a buffer overflow. This bug was reported by Murray
McAllister of the Red Hat Security Response Team.
CVE-2016-8694 CVE-2016-8695 CVE-2016-8696
Multiple NULL pointer dereferences in bm_readbody_bmp. This bug was
discovered by Agostino Sarubbo of Gentoo.
CVE-2016-8697
Division by zero in bm_new. This bug was discovered by Agostino
Sarubbo of Gentoo.
CVE-2016-8698 CVE-2016-8699 CVE-2016-8700 CVE-2016-8701 CVE-2016-8702
CVE-2016-8703
Multiple heap-based buffer overflows in bm_readbody_bmp. This bug was
discovered by Agostino Sarubbo of Gentoo.
For Debian 7 'Wheezy', these problems have been fixed in version
1.10-1+deb7u1.
We recommend that you upgrade your potrace packages.
