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 Reader HTML to PDF conversion getMatchedCSSRules use-after-free attempt
This event is generated when a crafted HTML file designed to crash Adobe Reader traverses the network. Impact: Attempted User Privilege Gain Details: This vulnerability is due to a dangling pointer that leads to a use after free vulnerability in the HTML to PDF conversion engine. Specifically, the vulnerability is triggered by a crafted HTML file which leads to a temporal safety violation if it is possible to perform read / write dereferences on the dangling pointer. This instance causes access violation exception because of the computation within the HTML to PDF engine related to Document Object window functionality that dereferences the dangling pointer. A constraint for exploitation of this vulnerability is that the memory area of the freed (i.e., old) object is reused by another object. The mismatch between the old and the new object can provide attacker with an unintended memory read access. Ease of Attack:
