Xpdf » Xpdf » 0.91 : Security Vulnerabilities, CVEs, CVSS score >= 6

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.

The patch for integer overflow vulnerabilities in Xpdf 2.0 and 3.0 (CVE-2004-0888) is incomplete for 64-bit architectures on certain Linux distributions such as Red Hat, which could leave Xpdf users exposed to the original vulnerabilities.

Buffer overflow in the Decrypt::makeFileKey2 function in Decrypt.cc for xpdf 3.00 and earlier allows remote attackers to execute arbitrary code via a PDF file with a large /Encrypt /Length keyLength value.

Multiple integer overflows in xpdf 3.0, and other packages that use xpdf code such as CUPS, allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code, a different set of vulnerabilities than those identified by CVE-2004-0888.

Multiple integer overflows in xpdf 2.0 and 3.0, and other packages that use xpdf code such as CUPS, gpdf, and kdegraphics, allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code, a different set of vulnerabilities than those identified by CVE-2004-0889.

Integer overflow in pdftops, as used in Xpdf 2.01 and earlier, xpdf-i, and CUPS before 1.1.18, allows local users to execute arbitrary code via a ColorSpace entry with a large number of elements, as demonstrated by cups-pdf.
