Description

A flaw was found in rsync. A network attacker can exploit an off-by-one out-of-bounds stack write vulnerability in the `establish_proxy_connection()` function by sending a malformed HTTP proxy response. This occurs when the `RSYNC_PROXY` environment variable is set and the attacker sends a response line of 1023 or more bytes without a newline terminator. This can corrupt stack memory, potentially leading to a Denial of Service (DoS).
