Vulnerability Details

CVEID:CVE-2021-25215
**DESCRIPTION:**ISC BIND is vulnerable to a denial of service, caused by an assertion failure while answering queries for DNAME records. By sending a query for DNAME records, an attacker could exploit this vulnerability to trigger a failed assertion check and terminate the named process.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/200960 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2020-25648
**DESCRIPTION:**Mozilla Network Security Services (NSS), as used in Mozilla Firefox is vulnerable to a denial of service, caused by improper handling of CCS (ChangeCipherSpec) messages in TLS. By sending specially-crafted CCS messages, a remote attacker could exploit this vulnerability to cause the system to crash.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/190416 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2020-25692
**DESCRIPTION:**OpenLDAP is vulnerable to a denial of service, caused by a NULL pointer dereference. By sending a specially crafted TCP packet, a remote attacker could exploit this vulnerability to cause slapd to crash.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/191968 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2020-8625
**DESCRIPTION:**ISC BIND is vulnerable to a buffer overflow, caused by improper bounds checking by the SPNEGO implementation. By setting valid values for the tkey-gssapi-keytab or tkey-gssapi-credentialconfiguration options, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the named process to crash.
CVSS Base score: 8.1
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/196959 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2021-27363
**DESCRIPTION:**Linux Kernel could allow a local authenticated attacker to obtain sensitive information, caused by a kernel pointer leak when show_transport_handle function in drivers/scsi/scsi_transport_iscsi.c is called. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain the address of the iscsi_transport structure information, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/197857 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)

CVEID:CVE-2021-27364
**DESCRIPTION:**Linux Kernel could allow a local authenticated attacker to execute arbitrary commands on the system, caused by a flaw in the iscsi_if_recv_msg function in drivers/scsi/scsi_transport_iscsi.c. By sending specially-crafted Netlink messages, an attacker could exploit this vulnerability to connect to the iscsi NETLINK socket and send arbitrary commands to the kernel.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/197858 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2021-27365
**DESCRIPTION:**Linux Kernel could allow a local authenticated attacker to obtain sensitive information, caused by an issue when certain iSCSI data structures do not have appropriate length constraints or checks, and can exceed the PAGE_SIZE value. By sending a specially-crafted Netlink message, an attacker could exploit this vulnerability to obtain memory information, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/197859 for the current score.
