Security Advisories
The nekohtml package is vulnerable to Denial of Service due to Uncontrolled Resource Consumption. The scanPI() function in the HTMLScanner class mishandles the parsing of a processing instruction while scanning a document. An attacker can leverage this behavior using a specially-crafted HTML composition, which has a ? or / character at the end of the processed instruction, to cause an infinite loop that appends a byte in a buffer in every cycle, causing a java.lang.OutOfMemoryError exception.
The Oxygen products incorporate nekohtml as a third-party library. This advisory was opened to address the potential impact of this third-party library vulnerability.
None
