Vulnerability details
The vulnerability allows a remote attacker to inject arbitrary protocol elements into the decompiler's input stream and cause a denial of service.
The vulnerability exists due to integer truncation in the PackedDecode::skipAttribute and PackedDecode::skipAttributeRemaining functions when processing string attributes in the packed binary format. A remote attacker can craft input for a victim to process with an encoded string length such as 0x100000000, which is truncated from 64 bits to 32 bits, causing the parser to skip zero bytes and interpret attacker-controlled string content as legitimate attributes and elements, corrupting parser state and potentially causing crashes or undefined behavior.
