The shared memory manager (associated with pre-authentication compression)
in sshd in OpenSSH before 7.4 does not ensure that a bounds check is
enforced by all compilers, which might allows local users to gain
privileges by leveraging access to a sandboxed privilege-separation
process, related to the m_zback and m_zlib data structures.

Notes
| Author | Note |
|---|---|
| ratliff | Mitigating circumstances noted in the release notes: This could potentially allow attacks against the privileged monitor process from the sandboxed privilege-separation process (a compromise of the latter would be required first). also “pre-auth compression has been disabled by default in sshd for >10 years.” |
