CVE-2016-10012

7.8 highEPSS 1.3%

High (7.8) in openbsd openssh. EPSS 1.3% chance of exploitation in the next 30 days.

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.
