Fedora EPEL Update Notification
FEDORA-EPEL-2017-87be2d4d20
2017-08-31 13:59:47.318589
--------------------------------------------------------------------------------
Name : potrace
Product : Fedora EPEL 6
Version : 1.15
Release : 1.el6
URL :
http://potrace.sourceforge.net
Summary : Transform bitmaps into vector graphics
Description :
Potrace is a utility for tracing a bitmap, which means, transforming a bitmap
into a smooth, scalable image. The input is a bitmap (PBM, PGM, PPM, or BMP
format), and the default output is an encapsulated PostScript file (EPS).
A typical use is to create EPS files from scanned data, such as company or
university logos, handwritten notes, etc. The resulting image is not "jaggy"
like a bitmap, but smooth. It can then be rendered at any resolution.
Potrace can currently produce the following output formats: EPS, PostScript,
PDF, SVG (scalable vector graphics), Xfig, Gimppath, and PGM (for easy
antialiasing). Additional backends might be added in the future.
Mkbitmap is a program distributed with Potrace which can be used to pre-process
the input for better tracing behavior on greyscale and color images.

Update Information:
This release consists of bugfixes and minor portability improvements. Some
potential buffer overflows and arithmetic overflows were fixed, including
CVE-2017-12067. A bug triggered by very large bitmaps has been fixed.
