Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
EUVDB-ID: #VU55315
Risk: Medium
CVSSv3.1:
CVE-ID: CVE-2021-23343
CWE-ID:
CWE-185 - Incorrect Regular Expression
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient input validation in splitDeviceRe, splitTailRe, and splitPathRe regular expressions. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.
Update the affected package nodejs8 to the latest version.

Risk: Medium
CVSSv3.1:
CVE-ID: CVE-2021-32803
CWE-ID:
CWE-36 - Absolute Path Traversal
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to overwrite arbitrary files on the system.
The vulnerability exists due to a logic issue when extracting tar files that contained both a directory
and a symlink with the same name as the directory. This order of
operations resulted in the directory being created and added to the node-tar
directory cache. When a directory is present in the directory cache,
subsequent calls to mkdir for that directory are skipped. However, this
is also where node-tar
checks for symlinks occur.
By first creating a directory, and then replacing that directory with a symlink, it was thus possible to bypass node-tar
symlink checks on directories, essentially allowing an untrusted tar
file to symlink into an arbitrary location and subsequently extracting
arbitrary files into that location, thus allowing arbitrary file
creation and overwrite.
Update the affected package nodejs8 to the latest version.

EUVDB-ID: #VU58205
Risk: Medium
CVSSv3.1:
CVE-ID: CVE-2021-32804
CWE-ID:
CWE-36 - Absolute Path Traversal
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to overwrite arbitrary files on the system.
The vulnerability exists due to a logic issue when file paths contained repeated path roots such as ////home/user/.bashrc
. node-tar
would only strip a single path root from such paths. When given an
absolute file path with repeating path roots, the resulting path (e.g. ///home/user/.bashrc
) would still resolve to an absolute path, thus allowing arbitrary file creation and overwrite.
Update the affected package nodejs8 to the latest version.

Risk: Medium
CVSSv3.1:
CVE-ID: CVE-2021-3807
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input when matching crafted invalid ANSI escape codes in ansi-regex. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
