All Xpdf users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose '>=app-text/xpdf-3.00-r8' All GPdf users should also upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose '>=app-text/gpdf-2.8.2' http://www.securityspace.com/smysecure/catid.html?in=GLSA%20200501-28 http://bugs.gentoo.org/show_bug.cgi?id=77888 http://bugs.gentoo.org/show_bug.cgi?id=78128 http://www.idefense.com/application/poi/display?id=186&type=vulnerabilities&flashstatus=true

A stack overflow was discovered in Xpdf, potentially resulting in the execution of arbitrary code. GPdf includes Xpdf code and therefore is vulnerable to the same issue.
