CVE-2016-10012 (GCVE-0-2016-10012)

Vulnerability from cvelistv5 – Published: 2017-01-05 00:00 – Updated: 2026-05-29 20:48

Summary

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.

Severity
