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 part of 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. The vulnerability is caused by a buffer access with an incorrect length value when processing TIFF files embedded within an XPS document. Crafted TIFF image input causes a mismatch between allocated buffer size and the access allowed by the computation. If an attacker can adequately control the accessible memory then this vulnerability can be leveraged to achieve arbitrary code execution.

This vulnerability is an instance of a security bypass vulnerability for a certain file-type extension. Acrobat maintains both a blacklist and whitelist (the user can specify an allowed attachment). However, any file extensions that are neither on the blacklist nor the whitelist can still be opened after displaying a warning prompt.

This vulnerability is an instance of a type confusion overflow vulnerability in the graphics rendering engine.

This vulnerability is due to a computation that accesses a pointer that has not been initialized; the computation occurs during internal AST thread manipulation. In this case, a computation defines a read from an unexpected memory location. Therefore, an attacker might be able to read sensitive portions of memory.

This vulnerability is due to a computation that accesses a pointer that has not been initialized in the main DLL. In this case, a computation defines a read from an unexpected memory location. Therefore, an attacker might be able to read sensitive portions of memory.

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 the MakeAccessible plugin. 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.

This issue is due to an untrusted pointer dereference in the JavaSscript API engine. In this scenario, the JavaScript input is crafted in 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.

The vulnerability is caused by a buffer over-read in the JPEG 2000 module. An invalid JPEG 2000 input code stream leads to a computation where the pointer arithmetic results in a location outside valid memory locations belonging to the buffer. An attack can be used to obtain sensitive information, such as object heap addresses, etc.
