FILE-OTHER -- Snort detected traffic targeting vulnerabilities in a file type that does not require enough rule coverage to have its own category.
FILE-OTHER Adobe Acrobat Pro EMF EmfPlusDrawRects record out of bounds read attempt
This event is generated when an out-of-bounds memory read attempt is detected with EMF files in Adobe Acrobat Pro Impact: Attempted User Privilege Gain Details: This vulnerability occurs as a result of computation that reads data that is past the end of the target buffer; the computation is part of image conversion module that handles Enhanced Metafile Format Plus(EMF+) data. A malformed input that specifies rectangle graphics leads to flawed computation that involves pointer offset arithmetic which does not adequately account for the buffer boundaries. The use of an invalid (out-of-range) pointer offset during access of internal data structure array that represents a base-line graphics object causes the vulnerability. A successful attack can lead to sensitive data exposure. Ease of Attack: Medium

Buffer Overflow
Buffer Overflows occur when a memory location is filled past its expected boundaries. Computer attackers target systems without proper terminating conditions on buffers, which then write the additional information in other locations in memory, overwriting what is there. This could corrupt the data, making the system behave erratically or crash. The new information could include malicious executable code, which might be executed.
