Vulnerability Details

CVEID:CVE-2021-34558
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by the failure to properly assert that the type of public key in an X.509 certificate matches the expected type in the crypto/tls package. By persuading a victim to connect to a specially-crafted TLS server, a remote attacker could exploit this vulnerability to cause a TLS client to panic.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/205578 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H)

CVEID:CVE-2020-29652
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by a NULL pointer dereference in the golang.org/x/crypto/ssh component. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to cause a denial of service.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/193622 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-2020-28851
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by improper input validation while parsing the -u- extension in language.ParseAcceptLanguage. By sending a specially-crafted HTTP Accept-Language header, a remote attacker could exploit this vulnerability to cause an index out of range panic.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/194162 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-2020-28852
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by improper input validation while processing a BCP 47 tag in language.ParseAcceptLanguage. By sending a specially-crafted HTTP Accept-Language header, a remote attacker could exploit this vulnerability to cause a slice bounds out of range panic.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/194163 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-2021-31525
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by a flaw in net/http. By sending a specially-crafted header to ReadRequest or ReadResponse. Server, Transport, and Client, a remote attacker could exploit this vulnerability to cause a (panic) denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/202709 for the current score.
