Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Affected versions of github.com/gotd/td before 0.145.1 are vulnerable to denial of service in the unencrypted message decoder. A remote, unauthenticated attacker can send a crafted small packet declaring a very large payload length, forcing a multi-gigabyte memory allocation that can exhaust CPU, memory, or cause termination. Upgrade to version 0.145.1 or later; the source lists no workaround other than avoiding exposure to untrusted peers.
