Gpdf

The FoFiType1::parse function in fofi/FoFiType1.cc in Xpdf 3.0.0, gpdf 2.8.2, kpdf in kdegraphics 3.3.1, and possibly other libraries and versions, does not check the return value of the getNextLine function, which allows context-dependent attackers to execute arbitrary code via a PDF file with a crafted Type 1 font that can produce a negative value, leading to a signed-to-unsigned integer conversion error and a buffer overflow.

Unspecified vulnerability in certain versions of xpdf after 3.00, as used in various products including (a) pdfkit.framework, (b) gpdf, (c) pdftohtml, and (d) libextractor, has unknown impact and user-assisted attack vectors, possibly involving errors in (1) gmem.c, (2) SplashXPathScanner.cc, (3) JBIG2Stream.cc, (4) JPXStream.cc, and/or (5) Stream.cc. NOTE: this description is based on Debian advisory DSA 979, which is based on changes that were made after other vulnerabilities such as CVE-2006-0301 and CVE-2005-3624 through CVE-2005-3628 were fixed. Some of these newer fixes appear to be security-relevant, although it is not clear if they fix specific issues or are defensive in nature.
