### Summary Allocating an untrusted amount of memory allows any unauthenticated user to OOM a russh server. ### Details An SSH packet consists of a 4-byte big-endian length, followed by a byte stream of this length. After parsing and potentially decrypting the 4-byte length, russh allocates enough memory for this bytestream, as a performance optimization to avoid reallocations later. https://github.com/Eugeny/russh/blob/4eaa080e7532662023f75e8fff45b743fe607f8c/russh/src/cipher/mod.rs#L254 But this length is entirely untrusted and can be set to any value by the client, causing this much memory to be allocated, which will cause the process to OOM within a few such requests. RFC 4253 contains an explicit section on packet length limits: https://datatracker.ietf.org/doc/html/rfc4253#section-6.1 > However, implementations SHOULD check that the packet length is reasonable in order for the implementation to avoid denial of service and/or buffer overflow attacks. ### PoC Running the `...
Red Hat Security Advisory 2024-5306-03 - An update for orc is now available for Red Hat Enterprise Linux 8. Issues addressed include a buffer overflow vulnerability.
Ubuntu Security Notice 6954-1 - Markus Frank and Fiona Ebner discovered that QEMU did not properly handle certain memory operations, leading to a NULL pointer dereference. An authenticated user could potentially use this issue to cause a denial of service. Xiao Lei discovered that QEMU did not properly handle certain memory operations when specific features were enabled, which could lead to a stack overflow. An attacker could potentially use this issue to leak sensitive information.
