Vulnerability Details

CVEID: CVE-2018-7183 DESCRIPTION: NTP is vulnerable to a buffer overflow, caused by improper bounds checking by the decodearr function. By leveraging an ntpq query and sending a response with a crafted array, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 5.6
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/140092&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L)

CVEID: CVE-2018-7185 DESCRIPTION: NTP is vulnerable to a denial of service. By sending specially crafted packets, a remote authenticated attacker could exploit this vulnerability to reset authenticated interleaved association.
CVSS Base Score: 3.1
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/139783&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2018-7170 DESCRIPTION: NTP could allow a remote authenticated attacker to bypass security restrictions, caused by a Sybil attack. By creating many ephemeral associations, an attacker could exploit this vulnerability to win the clock selection of ntpd and modify a victim’s clock.
CVSS Base Score: 3.1
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/139786&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N)

CVEID: CVE-2018-7182 DESCRIPTION: NTP could allow a remote attacker to obtain sensitive information, caused by a leak in the ctl_getitem() function. By sending a specially crafted mode 6 packet, an attacker could exploit this vulnerability to read past the end of its buffer.
CVSS Base Score: 5.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/139785&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2018-7184 DESCRIPTION: NTP is vulnerable to a denial of service, caused by the failure of the interleaved symmetric mode to recover from bad state. By sending specially crafted packets, a remote authenticated attacker could exploit this vulnerability to cause a denial of service.
CVSS Base Score: 3.1
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/139784&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2018-0737 DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive information, caused by a cache-timing side channel attack in the RSA Key generation algorithm. An attacker with access to mount cache timing attacks during the RSA key generation process could exploit this vulnerability to recover the private key and obtain sensitive information.
CVSS Base Score: 3.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/141679&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2017-3738 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. An attacker could exploit this vulnerability to obtain information about the private key. Note: In order to exploit this vulnerability, the server would have to share the DH1024 private key among multiple clients, which is no longer an option since CVE-2016-0701.
CVSS Base Score: 3.1
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/136078&gt; for the current score

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)

CVEID: CVE-2018-3640 DESCRIPTION: Multiple Intel CPU’s could allow a local attacker to obtain sensitive information, caused by utilizing sequences of speculative execution that perform speculative reads of system registers. By conducting targeted cache side-channel attacks, an attacker could exploit this vulnerability to determine the values stored in system registers. Note: This vulnerability is the Rogue System Register Read (RSRE), also known as Variant 3a.
CVSS Base Score: 4.3

CVEID: CVE-2018-3639 DESCRIPTION: Multiple Intel CPU’s could allow a local attacker to obtain sensitive information, caused by utilizing sequences of speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known. By conducting targeted cache side-channel attacks, an attacker could exploit this vulnerability to bypass security restrictions and gain read access to privileged memory. Note: This vulnerability is the Speculative Store Bypass (SSB), also known as Variant 4 or “SpectreNG”.
