openSUSE Security Update : openssh (openSUSE-2017-184)

Synopsis :

The remote openSUSE host is missing a security update.

Description :

This update for openssh fixes several issues.

These security issues were fixed :

- CVE-2016-8858: The kex_input_kexinit function in kex.c
allowed remote attackers to cause a denial of service
(memory consumption) by sending many duplicate KEXINIT
requests (bsc#1005480).

- CVE-2016-10012: The shared memory manager (associated
with pre-authentication compression) did not ensure that
a bounds check is enforced by all compilers, which might
allowed local users to gain privileges by leveraging
access to a sandboxed privilege-separation process,
related to the m_zback and m_zlib data structures
(bsc#1016370).

- CVE-2016-10009: Untrusted search path vulnerability in
ssh-agent.c allowed remote attackers to execute
arbitrary local PKCS#11 modules by leveraging control
over a forwarded agent-socket (bsc#1016366).

- CVE-2016-10010: When forwarding unix domain sockets with
privilege separation disabled, the resulting sockets
have be created as 'root' instead of the authenticated
user. Forwarding unix domain sockets without privilege
separation enabled is now rejected.

- CVE-2016-10011: authfile.c in sshd did not properly
consider the effects of realloc on buffer contents,
which might allowed local users to obtain sensitive
private-key information by leveraging access to a
privilege-separated child process (bsc#1016369).

These non-security issues were fixed :

- Adjusted suggested command for removing conflicting
server keys from the known_hosts file (bsc#1006221)

- Properly verify CIDR masks in configuration (bsc#1005893
bsc#1021626)
