Multiple Vulnerabilities in Adobe Reader and Adobe Acrobat Could Allow Remote Code Execution (APSB16-14)

ITS Advisory Number:

2016-082

Date(s) Issued:

Tuesday, May 10, 2016

Subject:

Multiple Vulnerabilities in Adobe Reader and Adobe Acrobat Could Allow Remote Code Execution (APSB16-14)

Overview:

Multiple vulnerabilities in Adobe Acrobat and Adobe Reader could allow for remote code execution. Adobe Acrobat and Reader allow a user to view, create, manipulate, print and manage files in Portable Document Format (PDF). Successful exploitation could potentially allow an attacker to take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full system rights.

Systems Affected:

Acrobat DC versions prior to 15.010.20060 for Windows and Macintosh
Acrobat Reader DC versions prior to 15.010.20060 for Windows and Macintosh
Acrobat DC versions prior to 15.006.30121 for Windows and Macintosh
Acrobat Reader DC versions prior to 15.006.30121 for Windows and Macintosh
Acrobat XI versions prior to 11.0.15 for Windows and Macintosh
Reader XI versions prior to 11.0.15 for Windows and Macintosh

Description:

Adobe Reader and Adobe Acrobat are prone to multiple vulnerabilities, the most severe of which could allow for remote code execution. These vulnerabilities are as follows:

These updates resolve use-after-free vulnerabilities that could lead to code execution (CVE-2016-1045, CVE-2016-1046, CVE-2016-1047, CVE-2016-1048, CVE-2016-1049, CVE-2016-1050, CVE-2016-1051, CVE-2016-1052, CVE-2016-1053, CVE-2016-1054, CVE-2016-1055, CVE-2016-1056, CVE-2016-1057, CVE-2016-1058, CVE-2016-1059, CVE-2016-1060, CVE-2016-1061, CVE-2016-1065, CVE-2016-1066, CVE-2016-1067, CVE-2016-1068, CVE-2016-1069, CVE-2016-1070, CVE-2016-1075, CVE-2016-1094, CVE-2016-1121, CVE-2016-1122, CVE-2016-4102, CVE-2016-4107).
These updates resolve heap buffer overflow vulnerabilities that could lead to code execution (CVE-2016-4091, CVE-2016-4092).
These updates resolve memory corruption vulnerabilities that could lead to code execution (CVE-2016-1037, CVE-2016-1063, CVE-2016-1064, CVE-2016-1071, CVE-2016-1072, CVE-2016-1073, CVE-2016-1074, CVE-2016-1076, CVE-2016-1077, CVE-2016-1078, CVE-2016-1080, CVE-2016-1081, CVE-2016-1082, CVE-2016-1083, CVE-2016-1084, CVE-2016-1085, CVE-2016-1086, CVE-2016-1088, CVE-2016-1093, CVE-2016-1095, CVE-2016-1116, CVE-2016-1118, CVE-2016-1119, CVE-2016-1120, CVE-2016-1123, CVE-2016-1124, CVE-2016-1125, CVE-2016-1126, CVE-2016-1127, CVE-2016-1128, CVE-2016-1129, CVE-2016-1130, CVE-2016-4088, CVE-2016-4089, CVE-2016-4090, CVE-2016-4093, CVE-2016-4094, CVE-2016-4096, CVE-2016-4097, CVE-2016-4098, CVE-2016-4099, CVE-2016-4100, CVE-2016-4101, CVE-2016-4103, CVE-2016-4104, CVE-2016-4105).
These updates resolve an integer overflow vulnerability that could lead to code execution (CVE-2016-1043).
These updates resolve memory leak vulnerabilities (CVE-2016-1079, CVE-2016-1092).
These updates resolve an information disclosure issue (CVE-2016-1112).
These updates resolve various methods to bypass restrictions on Javascript API execution (CVE-2016-1038, CVE-2016-1039, CVE-2016-1040, CVE-2016-1041, CVE-2016-1042, CVE-2016-1044, CVE-2016-1062, CVE-2016-1117).
These updates resolve vulnerabilities in the directory search path used to find resources that could lead to code execution (CVE-2016-1087, CVE-2016-1090, CVE-2016-4106).

Successful exploitation could potentially allow an attacker to take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full system rights.
