netty: Netty: Denial of Service via HTTP/2 CONTINUATION frame flood

A flaw was found in Netty. A remote user can trigger a Denial of Service DoS against a Netty HTTP/2 server by sending a flood of CONTINUATION frames. The server's lack of a limit on these frames, coupled with a bypass of size-based mitigations using zero-byte frames, allows an attacker to consume...

GHSA-HM49-WCQC-G2XG net-imap vulnerable to command Injection via "raw" arguments to multiple commands

Summary Several Net::IMAP commands accept a raw string argument that is sent to the server without validation or escaping. If this string is derived from user-controlled input, it may contain contain CRLF sequences, which an attacker can use to inject arbitrary IMAP commands. Details Net::IMAP's...

GHSA-Q2MW-FVJ9-VVCW net-imap has quadratic complexity when reading response literals

Summary Net::IMAP::ResponseReader has quadratic time complexity when reading large responses containing many string literals. A hostile server can send responses which are crafted to exhaust the client's CPU for a denial of service attack. Details For each literal in a response, ResponseReader...

net-imap vulnerable to STARTTLS stripping via invalid response timing

Summary A man-in-the-middle attacker can cause Net::IMAPstarttls to return "successfully", without starting TLS. Details When using Net::IMAPstarttls to upgrade a plaintext connection to use TLS, a man-in-the-middle attacker can inject a tagged OK response with an easily predictable tag. By sendi...
