SynopsisThe remote SSH client may be affected by multiple vulnerabilities.
DescriptionVersions of OpenSSH prior to 7.1p2 are affected by multiple vulnerabilities:
- Using a specially crafted SSH server, a context-dependent attacker can disclose sensitive memory contents when the client authenticates to the server, such as the client's private SSH keys. (CVE-2016-0777)
- An unspecified overflow condition exists that is triggered as user-supplied input is not properly validated. With a specially crafted SSH server, a context-dependent attacker can cause a buffer overflow, potentially allowing the execution of arbitrary code. (CVE-2016-0778)
Note: NNM has solely relied on the banner of the SSH client to perform this check. Any backported patches or workarounds such as recompiling or edited configurations are not observable through the banner.
- A vulnerability exists that allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via crafted network traffic. (CVE-2016-1907)
SolutionUpgrade to OpenSSH version 7.1p2 or later.
