  "title": "rsync 3.1.0 \u003C 3.5.0\u00A0Signed Integer Overflow via MSG_IO_TIMEOUT",
  "description": "rsync 3.1.0 before 3.5.0\u00A0contains a signed integer overflow vulnerability in the I/O timeout implementation that allows attackers to permanently disable connection timeouts by injecting MSG_IO_TIMEOUT messages carrying non-positive (zero or negative) values. Attackers can craft malicious MSG_IO_TIMEOUT messages that cause the timeout variable to wrap to a non-positive value, preventing the timeout check from firing and enabling idle or stalled connections to hold daemon slots indefinitely, leading to resource exhaustion.",
