Alpine: multiple openssh packages: security update to 7.5_p1-r8

high Tenable Cloud Security Plugin ID 424308

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- Untrusted search path vulnerability in ssh-agent.c in ssh-agent in OpenSSH before 7.4 allows remote
attackers to execute arbitrary local PKCS#11 modules by leveraging control over a forwarded agent-socket.
(CVE-2016-10009)

- sshd in OpenSSH before 7.4, when privilege separation is not used, creates forwarded Unix-domain sockets
as root, which might allow local users to gain privileges via unspecified vectors, related to
serverloop.c. (CVE-2016-10010)

- authfile.c in sshd in OpenSSH before 7.4 does not properly consider the effects of realloc on buffer
contents, which might allow local users to obtain sensitive private-key information by leveraging access
to a privilege-separated child process. (CVE-2016-10011)

- 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. (CVE-2016-10012)

- The process_open function in sftp-server.c in OpenSSH before 7.6 does not properly prevent write
operations in readonly mode, which allows attackers to create zero-length files. (CVE-2017-15906)
