Severity: Normal Title: Xpdf, CUPS: Multiple integer overflows Date: October 21, 2004 ID: 200410-20

Synopsis ========
Multiple integer overflows were discovered in Xpdf, potentially resulting in execution of arbitrary code upon viewing a malicious PDF file. 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"
