Adobe Reader 7 and Acrobat 7 before 7.1.3, Adobe Reader 8 and Acrobat 8 before 8.1.6, and Adobe Reader 9 and Acrobat 9 before 9.1.2 allow attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code via a PDF document with a crafted TrueType font.

Multiple unspecified vulnerabilities in Adobe Reader 7 and Acrobat 7 before 7.1.3, Adobe Reader 8 and Acrobat 8 before 8.1.6, and Adobe Reader 9 and Acrobat 9 before 9.1.2 have unknown impact and attack vectors, related to "Adobe internally discovered issues."

Heap-based buffer overflow in the JBIG2 filter in Adobe Reader 7 and Acrobat 7 before 7.1.3, Adobe Reader 8 and Acrobat 8 before 8.1.6, and Adobe Reader 9 and Acrobat 9 before 9.1.2 allows remote attackers to execute arbitrary code via a crafted file that triggers memory corruption.

Heap-based buffer overflow in Adobe Acrobat Reader and Acrobat Professional 7.1.0, 8.1.3, 9.0.0, and other versions allows remote attackers to execute arbitrary code via a PDF file containing a JBIG2 stream with a size inconsistency related to an unspecified table.

Adobe Acrobat Reader 9 before 9.1, 8 before 8.1.4, and 7 before 7.1.1 might allow remote attackers to trigger memory corruption and possibly execute arbitrary code via unknown attack vectors related to JBIG2, a different vulnerability than CVE-2009-0193 and CVE-2009-1061.

The Javascript API in Adobe Acrobat Professional 7.0.9 and possibly 8.1.1 exposes a dangerous method, which allows remote attackers to execute arbitrary commands or trigger a buffer overflow via a crafted PDF file that invokes app.checkForUpdate with a malicious callback function.
