RHBA-2011:0527 - ghostscript bug fix update

Synopsis

ghostscript bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated ghostscript packages that fix various bugs are now available for Red Hat Enterprise Linux 6.

Description

The Ghostscript suite provides a PostScript interpreter, a set of C procedures (the Ghostscript library, which implements the graphics capabilities in the PostScript language), and an interpreter for PDF files. Ghostscript translates PostScript code into many common, bitmapped formats, like those understood by most printers and displays. This enables users to display PostScript files and print them on non-PostScript printers.

This update fixes the following bugs:

• Previously, including a large JBIG2 compressed image in the PDF input file could cause the pdf2ps conversion utility to terminate unexpectedly with a segmentation fault. This was caused by the fact that the result of the "jbig2_image_new" function call was not always checked properly. This error has been fixed, and the inclusion of JBIG2 images no longer causes pdf2ps to crash. (BZ#621118)

• Due to incorrect object management, Ghostscript could attempt to read from uninitialized memory, which could lead to a segmentation fault. This update applies a backported patch that addresses this issue, and Ghostscript no longer crashes. (BZ#629562)

• The Fontmap.local file installed with the ghostscript package allows a system administrator to override font substitutions. However, previous versions of the Ghostscript suite did not use this file at all. This error has been fixed, and the file is now used as expected. (BZ#629941)

• Previously, using the ps2pdf utility to convert a PostScript file to the PDF format caused the resulting document to be created without working hyperlinks. This update applies an upstream patch that resolves this issue, and ps2pdf now crates PDF files with correct hyperlinks. (BZ#675692)

All users of ghostscript are advised to upgrade to these updated packages, which fix these bugs.
