Vulnerability Details

CVEID:CVE-2021-4034
**DESCRIPTION:**Polkit could allow a local authenticated attacker to gain elevated privileges on the system, caused by incorrect handling of the argument vectors in the pkexec utility. By crafting environment variables in a specific way, an attacker could exploit this vulnerability to execute commands with root privileges.
CVSS Base score: 7.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/218087 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-2022-21681
**DESCRIPTION:**Node.js marked module is vulnerable to a denial of service, caused by a regular expression denial of service (ReDoS) flaw in inline.reflinkSearch. By sending a specially-crafted regex input, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/217320 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-2022-21680
**DESCRIPTION:**Node.js marked module is vulnerable to a denial of service, caused by a regular expression denial of service (ReDoS) flaw in block.def. By sending a specially-crafted regex input, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/217319 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-2022-0235
**DESCRIPTION:**Node.js node-fetch could allow a remote authenticated attacker to obtain sensitive information, caused by a flaw when fetching a remote url with Cookie. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/217758 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)

CVEID:CVE-2021-41617
**DESCRIPTION:**OpenSSH could allow a local attacker to gain elevated privileges on the system, caused by an error in sshd when certain non-default configurations are used. By executing an AuthorizedKeysCommand or AuthorizedPrincipalsCommand, where a AuthorizedKeysCommandUser or AuthorizedPrincipalsCommandUser directive has been set to run the command as a non-root user, an attacker could exploit this vulnerability to gain privileges associated with group memberships of the sshd process.
CVSS Base score: 7.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/210062 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)

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

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
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/216563 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N)

**Third Party Entry:**218243
**DESCRIPTION:**The Node.js uglify-js module is vulnerable to a denial of service, caused by an error in the string_template and the decode_template functions. By sending a regular expression, an attacker could exploit this vulnerability to cause a denial of service.
CVSS Base score: 5.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/218243 for the current score.
