Adobe Reader and Acrobat Arbitrary Integer Overflow Vulnerability
Adobe · Reader and Acrobat
End of lifeAdobe Reader/Acrobat 9 reached End of lifeThe vendor no longer ships security fixes. Remove or isolate the product instead of waiting for a patch. on 26 Jun 2013. No patch is coming: remove or isolate it.
The flaw is an integer overflow in the Reader and Acrobat products from Adobe, specifically in the 9.x, 10.x, and 11.x branches before the fixed releases of 9.5.5, 10.1.7, and 11.0.03. An attacker who can reach a target through unspecified vectors can execute arbitrary code.
Integer overflow in Adobe Reader and Acrobat 9.x before 9.5.5, 10.x before 10.1.7, and 11.x before 11.0.03 allows attackers to execute arbitrary code via unspecified vectors, a different vulnerability than CVE-2013-2727.
