stream-json: JSONC parser and verifier re-scan the whole accumulated comment on every input chunk

Summary The JSONC parser stream-json/jsonc/parser.js and verifier stream-json/jsonc/verifier.js scan a comment for its terminator starting from the comment's opening / on every input chunk. When a comment doesn't finish inside the current buffer, the scanner returns the comment's start offset and...

jackson-databind: Jackson-databind: Denial of Service via deeply nested JSON processing

A flaw was found in jackson-databind, a general-purpose data-binding library for Jackson Data Processor. A remote attacker can exploit this vulnerability by sending deeply nested JSON JavaScript Object Notation data to a service that reads and processes it. This can lead to a Denial of Service Do...

com.fasterxml.jackson.core/jackson-core: tools.jackson.core/jackson-core: jackson-core: Denial of Service via incomplete fix in async JSON parser

A flaw was found in jackson-core. A remote attacker can exploit an incomplete fix in the non-blocking JSON parser by streaming specially crafted JSON data in small chunks. This bypasses the intended number length constraint, causing the parser to accumulate excessive memory per connection. This...
