There is no fixed version for busybox.
Overview
Affected versions of this package are vulnerable to Incorrect Calculation of Buffer Size via the ssl_server process. An attacker can cause a crash by sending a specially crafted ClientKeyExchange message to the TLS server, resulting in a denial of service. This is only exploitable if the ssl_server applet is present and used, as it is not shipped in certain distributions and system-level mitigations may prevent further exploitation.
Workaround
This vulnerability can be mitigated by not using the ssl_server applet in production environments and ensuring system-level exploit mitigations (ASLR, PIE, RELRO, stack protectors) are enabled.
