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 over-read in the True Type2 Font parsing module. A corrupted cmap table input 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.
The product reads data past the end, or before the beginning, of the intended buffer.
