Vulnerability Details

CVEID:CVE-2021-3712
**DESCRIPTION:**OpenSSL could allow a remote attacker to obtain sensitive information, caused by an out-of-bounds read when processing ASN.1 strings. By sending specially crafted data, an attacker could exploit this vulnerability to read contents of memory on the system or perform a denial of service attack.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/208073 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L)

CVEID:CVE-2021-37713
**DESCRIPTION:**Node.js tar module could allow a local attacker to execute arbitrary code on the system, caused by insufficient logic on Windows systems when extracting tar files that contained a path that was not an absolute path, but specified a drive letter different from the extraction target. An attacker could exploit this vulnerability to create or overwrite arbitrary files and execute arbitrary code on the system.
CVSS Base score: 8.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/208451 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N)

CVEID:CVE-2021-39134
**DESCRIPTION:**Node.js @npmcli/arborist module could allow a local attacker to launch a symlink attack, caused by the failure of multiple dependencies to coexist within the same level in the node_modules hierarchy. A local attacker could exploit this vulnerability by creating a symbolic link from a temporary file to various files on the system, which could allow the attacker to create and overwrite arbitrary files on the system with elevated privileges.
CVSS Base score: 8.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/208462 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N)

CVEID:CVE-2021-37712
**DESCRIPTION:**Node.js tar module could allow a local attacker to execute arbitrary code on the system, caused by an arbitrary file creation/overwrite vulnerability. By creating a directory, and then replacing that directory with a symlink that had a different apparent name that resolved to the same entry in the filesystem, an attacker could use an untrusted tar file to symlink into an arbitrary location and extract arbitrary files into that location to create or overwrite arbitrary files and execute arbitrary code on the system.
CVSS Base score: 8.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/208450 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N)

CVEID:CVE-2021-39135
**DESCRIPTION:**Node.js @npmcli/arborist module could allow a local attacker to launch a symlink attack. By replacing the node_modules folder of the root project or any of its dependencies with a symbolic link, an attacker could exploit this vulnerability to write package dependencies to any arbitrary location on the file system.
CVSS Base score: 8.2
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/208464 for the current score.
