HAPI FHIR: SHCParser DEFLATE infinite loop causes denial of service

A malformed Smart Health Card SHC JWT with zip: "DEF" and an empty or truncated DEFLATE payload causes SHCParser.inflate to loop forever. This allows an attacker who can submit SHC content for validation to pin a JVM worker thread indefinitely, causing denial of service...

Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop in the SSHMSGCHANNELOPEN and SSHMSGCHANNELOPENCONFIRMATION. An attacker can cause the asyncio event loop to freeze by supplying a sendpktsize value of zero, which leads to an infinite loop that prevents further processing ...

CVE-2026-62949

CVE-2026-62949 affects AsyncSSH , a Python asynchronous SSHv2 implementation. The flaw resides in _process_channel_open and _process_channel_open_confirmation in asyncssh/connection.py, which accept a peer-supplied send_pktsize value of zero . When channel data reaches SSHChannel._flush_send_buf,...
