Fedora Update Notification

FEDORA-2017-d7739ff31b

2017-08-15 15:09:05.882153

——————————————————————————–

Name : potrace

Product : Fedora 25

Version : 1.15

Release : 1.fc25

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.
