Vulnerability Details
CVEID: CVE-2021-44716
DESCRIPTION: Golang Go is vulnerable to a denial of service, caused by an uncontrolled memory consumption in the header canonicalization cache in net/http. By sending HTTP/2 requests, a remote attacker could exploit this vulnerability to consume all available memory resources.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/216553 for the current score.

CVEID: CVE-2021-44717
DESCRIPTION: Golang Go could allow a remote attacker to bypass security restrictions, caused by an error in the syscall.ForkExec() interface. By causing the erroneous closing of file descriptor 0 after file-descriptor exhaustion, an attacker could exploit this vulnerability to compromise data integrity and/or confidentiality in a somewhat uncontrolled way in programs linked with and using syscall.ForkExec().
CVSS Base score: 4.8
