1 CVE-2018-15919 200 +Info 2018-08-28 2018-12-22
5.0
None Remote Low Not required Partial None None
Remotely observable behaviour in auth-gss2.c in OpenSSH through 7.8 could be used by remote attackers to detect existence of users on a target system when GSS2 is in use. NOTE: the discoverer states 'We understand that the OpenSSH developers do not want to treat such a username enumeration (or "oracle") as a vulnerability.'
2 CVE-2018-15473 200 +Info 2018-08-17 2019-08-06
5.0
None Remote Low Not required Partial None None
OpenSSH through 7.7 is prone to a user enumeration vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c.
3 CVE-2018-14775 20 DoS 2018-08-01 2018-10-03
4.9
None Local Low Not required None None Complete
tss_alloc in sys/arch/i386/i386/gdt.c in OpenBSD 6.2 and 6.3 has a Local Denial of Service (system crash) due to incorrect I/O port access control on the i386 architecture.
4 CVE-2018-12438 320 2018-06-14 2018-08-09
1.9
None Local Medium Not required Partial None None
The Elliptic Curve Cryptography library (aka sunec or libsunec) allows a memory-cache side-channel attack on ECDSA signatures, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host.
5 CVE-2018-12437 320 2018-06-14 2018-08-09
1.9
None Local Medium Not required Partial None None
LibTomCrypt through 1.18.1 allows a memory-cache side-channel attack on ECDSA signatures, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host.
6 CVE-2018-12434 200 +Info 2018-06-14 2018-08-06
1.9
None Local Medium Not required Partial None None
LibreSSL before 2.6.5 and 2.7.x before 2.7.4 allows a memory-cache side-channel attack on DSA and ECDSA signatures, aka the Return Of the Hidden Number Problem or ROHNP. To discover a key, the attacker needs access to either the local machine or a different virtual machine on the same physical host.
7 CVE-2018-12433 320 2018-06-14 2018-08-09
1.9
None Local Medium Not required Partial None None
** DISPUTED ** cryptlib through 3.4.4 allows a memory-cache side-channel attack on DSA and ECDSA signatures, aka the Return Of the Hidden Number Problem or ROHNP. To discover a key, the attacker needs access to either the local machine or a different virtual machine on the same physical host. NOTE: the vendor does not include side-channel attacks within its threat model.
8 CVE-2018-8970 295 +Info 2018-03-24 2018-04-24
5.8
None Remote Medium Not required Partial Partial None
The int_x509_param_set_hosts function in lib/libcrypto/x509/x509_vpm.c in LibreSSL 2.7.0 before 2.7.1 does not support a certain special case of a zero name length, which causes silent omission of hostname verification, and consequently allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate. NOTE: the LibreSSL documentation indicates that this special case is supported, but the BoringSSL documentation does not.
9 CVE-2016-10708 476 DoS 2018-01-21 2019-06-26
5.0
None Remote Low Not required None None Partial
sshd in OpenSSH before 7.4 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence NEWKEYS message, as demonstrated by Honggfuzz, related to kex.c and packet.c.
