CUPS includes Xpdf code and therefore is vulnerable to the same issues. Background ========== Xpdf is an open source viewer for Portable Document Format (PDF) files. The Common UNIX Printing System (CUPS) is a cross-platform print spooler that includes some Xpdf code. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/xpdf <= 3.00-r2 >= 3.00-r3 2 net-print/cups <= 1.1.20-r3 >= 1.1.20-r4 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== Chris Evans discovered multiple integer overflow issues in Xpdf. Impact ====== An attacker could entice an user to open a specially-crafted PDF file, potentially resulting in execution of arbitrary code with the rights of the user running Xpdf. By enticing an user to directly print the PDF file to a CUPS printer, an attacker could also crash the CUPS spooler or execute arbitrary code with the rights of the CUPS spooler, which is usually the "lp" user. Workaround ========== There is no known workaround at this time. Resolution ========== All Xpdf users should upgrade to the latest version: # emerge sync # emerge -pv ">=app-text/xpdf-3.00-r3" # emerge ">=app-text/xpdf-3.00-r3" All CUPS users should also upgrade to the latest version: # emerge sync # emerge -pv ">=net-print/cups-1.1.20-r4" # emerge ">=net-print/cups-1.1.20-r4" References ========== [ 1 ] CAN-2004-0888 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0888 [ 2 ] CAN-2004-0889 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0889 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200410-20.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
