Background ========== Ghostscript is an interpreter for the PostScript language and the Portable Document Format (PDF). Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/ghostscript-gpl < 8.64-r2 >= 8.64-r2 2 app-text/ghostscript-gnu < 8.62.0 >= 8.62.0 3 app-text/ghostscript-esp <= 8.15.4-r1 Vulnerable! ------------------------------------------------------------------- NOTE: Certain packages are still vulnerable. Users should migrate to another package if one is available or wait for the existing packages to be marked stable by their architecture maintainers. ------------------------------------------------------------------- 3 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Jan Lieskovsky from the Red Hat Security Response Team discovered the following vulnerabilities in Ghostscript's ICC Library: * Multiple integer overflows (CVE-2009-0583). * Multiple insufficient bounds checks on certain variable sizes (CVE-2009-0584). Impact ====== 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. Workaround ========== There is no known workaround at this time. Resolution ========== 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.
