The Portable Document Format (PDF) specification does not provide any information regarding the concrete procedure of how to validate signatures. Consequently, an Incremental Saving vulnerability exists in multiple products. When an attacker uses the Incremental Saving feature to add pages or annotations, Body Updates are displayed to the user without any action by the signature-validation logic. This affects Foxit Reader before 9.4 and PhantomPDF before 8.3.9 and 9.x before 9.4. It also affects LibreOffice, Master PDF Editor, Nitro Pro, Nitro Reader, Nuance Power PDF Standard, PDF Editor 6 Pro, PDFelement6 Pro, PDF Studio Viewer 2018, PDF Studio Pro, Perfect PDF 10 Premium, and Perfect PDF Reader.

Foxit Reader before 5.3 on Windows XP and Windows 7 allows remote attackers to execute arbitrary code via a PDF document with a crafted attachment that triggers calculation of a negative number during processing of cross references.

Multiple unspecified vulnerabilities in Adobe Reader through 10.1.4 allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PDF document, related to "sixteen more crashes affecting Windows, OS X, or both systems."

Use-after-free vulnerability in t1lib 5.1.2 and earlier, as used in Xpdf before 3.02pl6, teTeX, and other products, allows remote attackers to cause a denial of service (application crash) via a PDF document containing a crafted Type 1 font that triggers an invalid memory write, a different vulnerability than CVE-2011-0764.

Off-by-one error in t1lib 5.1.2 and earlier, as used in Xpdf before 3.02pl6, teTeX, and other products, allows remote attackers to cause a denial of service (application crash) via a PDF document containing a crafted Type 1 font that triggers an invalid memory read, integer overflow, and invalid pointer dereference, a different vulnerability than CVE-2011-0764.

t1lib 5.1.2 and earlier, as used in Xpdf before 3.02pl6, teTeX, and other products, reads from invalid memory locations, which allows remote attackers to cause a denial of service (application crash) via a crafted Type 1 font in a PDF document, a different vulnerability than CVE-2011-0764.

t1lib 5.1.2 and earlier, as used in Xpdf before 3.02pl6, teTeX, and other products, uses an invalid pointer in conjunction with a dereference operation, which allows remote attackers to execute arbitrary code via a crafted Type 1 font in a PDF document, as demonstrated by testz.2184122398.pdf.

Adobe Flash Player 10.1.82.76 and earlier on Windows, Mac OS X, Linux, and Solaris and 10.1.92.10 on Android; authplay.dll in Adobe Reader and Acrobat 9.x before 9.4; and authplay.dll in Adobe Reader and Acrobat 8.x before 8.2.5 on Windows and Mac OS X allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors, as exploited in the wild in September 2010.

The default configuration of Adobe Reader and Acrobat 9.x before 9.3, and 8.x before 8.2 on Windows and Mac OS X, does not enable the Enhanced Security feature, which has unspecified impact and attack vectors, related to a "script injection vulnerability," as demonstrated by Acrobat Forms Data Format (FDF) behavior that allows cross-site scripting (XSS) by user-assisted remote attackers.

The 3D implementation in Adobe Reader and Acrobat 9.x before 9.3, and 8.x before 8.2 on Windows and Mac OS X, might allow attackers to execute arbitrary code via unspecified vectors, related to a "DLL-loading vulnerability."
