RHBA-2013:1624 - Bug Fix Advisory

Topic

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

Description

The Ghostscript suite contains utilities for rendering PostScript and PDF
documents. Ghostscript translates PostScript code to common, bitmap formats so
that the code can be displayed or printed.

This update fixes the following bugs:

• Due to a bug in a function that copies CID-keyed Type 2 fonts, document

conversion attempts sometimes caused the ps2pdf utility to terminate
unexpectedly with a segmentation fault. A patch has been provided to address
this bug so that the function now copies fonts properly and ps2pdf no longer
crashes when converting documents. (BZ#893775)

• Due to lack of support for the TPGDON option for JBIG2 encoded regions, some

PDF files were not displayed correctly. A patch has been provided to add this
support so that PDF files using the TPGDON option are now displayed correctly.
(BZ#916162)

• Previously, some PDF files with incomplete ASCII base-85 encoded images caused

the ghostscript utility to terminate with the following error:

/syntaxerror in ID

The problem occurred when the image ended with "~" (tilde) instead of "~>"
(tilde, right angle bracket) as defined in the PDF specification. Although this
is an improper encoding, an upstream patch has been applied, and ghostscript now
handles these PDF files without errors. (BZ#1006165)

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

Solution

Before applying this update, make sure all previously released errata relevant
to your system have been applied.
