What is CVE-2008-1693?
CVE-2008-1693 is a medium-severity memory corruption vulnerability in n/a, published on 18 Apr 2008. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
The CairoFont::create function in CairoFontEngine.cc in Poppler, possibly before 0.8.0, as used in Xpdf, Evince, ePDFview, KWord, and other applications, does not properly handle embedded fonts in PDF files, which allows remote attackers to execute arbitrary code via a crafted font object, related to dereferencing a function pointer associated with the type of this font object.
