Adobe Reader 8.1.4

Buffer overflow in the Atlcom.get_atlcom ActiveX control in gp.ocx in Adobe Download Manager, as used in Adobe Reader and Acrobat 8.x before 8.2 and 9.x before 9.3, allows remote attackers to execute arbitrary code via unspecified parameters.

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 customDictionaryOpen spell method in the JavaScript API in Adobe Reader 9.1, 8.1.4, 7.1.1, and earlier on Linux and UNIX allows remote attackers to cause a denial of service (memory corruption) or execute arbitrary code via a PDF file that triggers a call to this method with a long string in the second argument.
