Vulnerability Details

CVEID:CVE-2022-2879
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by the failure to set a limit on the maximum size of file headers by Reader.Read. By using a specially crafted archive, a remote attacker could exploit this vulnerability to exhaust all available memory resources.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/240560 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-2022-41715
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by the compilation of regular expressions from untrusted sources. A remote attacker could exploit this vulnerability to exhaust all available memory resources.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/240559 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-2022-2880
**DESCRIPTION:**Golang Go could allow a remote attacker to conduct query parameter smuggling, caused by the inclusion of unparseable parameters rejected by net/http in requests forwarded by ReverseProxy. An attacker could exploit this vulnerability to conduct query parameter smuggling.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/240561 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N)

CVEID:CVE-2022-41717
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by a flaw when handling HTTP/2 requests in the Go server. By sending a specially-crafted keys, a remote attacker could exploit this vulnerability to cause excessive memory growth, and results in a denial of service condition.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/241875 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID:CVE-2022-41716
**DESCRIPTION:**Golang Go could allow a remote attacker to bypass security restrictions, caused by improper checking for invalid environment variable values in syscall.StartProcess and os/exec.Cmd. By using a specially-crafted environment variable value, an attacker could exploit this vulnerability to set a value for a different environment variable.
CVSS Base score: 7.5
