Ghostscript is an interpreter for the PostScript language and the Portable Document Format (PDF).
Jan Lieskovsky from the Red Hat Security Response Team discovered the following vulnerabilities in Ghostscript's ICC Library:
A remote attacker could entice a user to open a specially crafted PostScript file containing images and a malicious ICC profile, possibly resulting in the execution of arbitrary code with the privileges of the user running the application.
There is no known workaround at this time.
All GPL Ghostscript users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/ghostscript-gpl-8.64-r2"
All GNU Ghostscript users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/ghostscript-gnu-8.62.0"
We recommend that users unmerge ESP Ghostscript and use GPL or GNU Ghostscript instead:
# emerge --unmerge "app-text/ghostscript-esp"
For installation instructions, see above.
