An issue was discovered in Adobe Acrobat and Reader: 2017.012.20098 and earlier versions, 2017.011.30066 and earlier versions, 2015.006.30355 and earlier versions, and 11.0.22 and earlier versions. This vulnerability is an instance of a use after free vulnerability in the JavaScript engine. The mismatch between an old and a new object can provide an attacker with unintended memory access -- potentially leading to code corruption, control-flow hijack, or an information leak attack. Successful exploitation could lead to arbitrary code execution.

An issue was discovered in Adobe Acrobat and Reader: 2017.012.20098 and earlier versions, 2017.011.30066 and earlier versions, 2015.006.30355 and earlier versions, and 11.0.22 and earlier versions. This issue is due to an untrusted pointer dereference in the XPS parsing module. In this scenario, the input is crafted in a way that the computation results in pointers to memory locations that do not belong to the relevant process address space. The dereferencing operation is a read operation, and an attack can result in sensitive data exposure.

An issue was discovered in Adobe Acrobat and Reader: 2017.012.20098 and earlier versions, 2017.011.30066 and earlier versions, 2015.006.30355 and earlier versions, and 11.0.22 and earlier versions. This vulnerability occurs as a result of a computation that reads data that is past the end of the target buffer; the computation is a part of Enhanced Metafile Format (EMF) processing within the image conversion module. The use of an invalid (out-of-range) pointer offset during access of internal data structure fields causes the vulnerability. A successful attack can lead to sensitive data exposure.

An issue was discovered in Adobe Acrobat and Reader: 2017.012.20098 and earlier versions, 2017.011.30066 and earlier versions, 2015.006.30355 and earlier versions, and 11.0.22 and earlier versions. This vulnerability leads to a stack-based buffer overflow condition in the internal Unicode string manipulation module. It is triggered by an invalid PDF file, where a crafted Unicode string causes an out of bounds memory access of a stack allocated buffer, due to improper checks when manipulating an offset of a pointer to the buffer. Attackers can exploit the vulnerability and achieve arbitrary code execution if they can effectively control the accessible memory.
