Synopsis ========
Poppler does not handle fonts inside PDF files safely, allowing for execution of arbitrary code.
Background ==========
Poppler is a cross-platform PDF rendering library originally based on Xpdf.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/poppler < 0.6.3 >= 0.6.3
Description ===========
Kees Cook from the Ubuntu Security Team reported that the CairoFont::create() function in the file CairoFontEngine.cc does not verify the type of an embedded font object inside a PDF file before dereferencing a function pointer from it.
Impact ======
A remote attacker could entice a user to open a specially crafted PDF file with a Poppler-based PDF viewer such as Gentoo's Xpdf, Epdfview, or Evince, potentially 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 Poppler users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/poppler-0.6.3"
References ==========
