"The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2022:0014 advisory.
Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:
CVE-2020-28469:
This affects the package glob-parent before 5.1.2. The enclosure regex used to check for strings ending in
enclosure containing path separator.
CVE-2020-7788:
This affects the package ini before 1.3.6. If an attacker submits a malicious INI file to an application
that parses it with ini.parse, they will pollute the prototype on the application. This can be exploited
further depending on the context.
CVE-2021-22959:
The parser in accepts requests with a space (SP) right after the header name before the colon. This can
lead to HTTP Request Smuggling (HRS) in llhttp < v2.1.4 and < v6.0.6.
CVE-2021-22960:
The parse function in llhttp < 2.1.4 and < 6.0.6. ignores chunk extensions when parsing the body of
chunked requests. This leads to HTTP Request Smuggling (HRS) under certain conditions.
CVE-2021-33502:
The normalize-url package before 4.5.1, 5.x before 5.3.1, and 6.x before 6.0.1 for Node.js has a ReDoS
(regular expression denial of service) issue because it has exponential performance for data: URLs.
CVE-2021-37701:
The npm package tar (aka node-tar) before versions 4.4.16, 5.0.8, and 6.1.7 has an arbitrary file
creation/overwrite and arbitrary code execution vulnerability. node-tar aims to guarantee that any file
whose location would be modified by a symbolic link is not extracted. This is, in part, achieved by
ensuring that extracted directories are not symlinks. Additionally, in order to prevent unnecessary stat
calls to determine whether a given path is a directory, paths are cached when directories are created.
This logic was insufficient when extracting tar files that contained both a directory and a symlink with
the same name as the directory, where the symlink and directory names in the archive entry used
backslashes as a path separator on posix systems. The cache checking logic used both `\` and `/`
characters as path separators, however `\` is a valid filename character on posix systems. 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. Additionally, a similar confusion could arise on case-insensitive
filesystems. If a tar archive contained a directory at `FOO`, followed by a symbolic link named `foo`,
then on case-insensitive file systems, the creation of the symbolic link would remove the directory from
the filesystem, but _not_ from the internal directory cache, as it would not be treated as a cache hit. A
subsequent file entry within the `FOO` directory would then be placed in the target of the symbolic link,
thinking that the directory had already been created. These issues were addressed in releases 4.4.16,
5.0.8 and 6.1.7. The v3 branch of node-tar has been deprecated and did not receive patches for these
issues. If you are still using a v3 release we recommend you update to a more recent version of node-tar.
If this is not possible, a workaround is available in the referenced GHSA-9r2w-394v-53qc.
CVE-2021-37712:
The npm package tar (aka node-tar) before versions 4.4.18, 5.0.10, and 6.1.9 has an arbitrary file
creation/overwrite and arbitrary code execution vulnerability. node-tar aims to guarantee that any file
whose location would be modified by a symbolic link is not extracted. This is, in part, achieved by
ensuring that extracted directories are not symlinks. Additionally, in order to prevent unnecessary stat
calls to determine whether a given path is a directory, paths are cached when directories are created.
This logic was insufficient when extracting tar files that contained both a directory and a symlink with
names containing unicode values that normalized to the same value. Additionally, on Windows systems, long
path portions would resolve to the same file system entities as their 8.3 short path counterparts. A
specially crafted tar archive could thus include a directory with one form of the path, followed by a
symbolic link with a different string that resolves to the same file system entity, followed by a file
using the first form. By first 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, 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. These issues were addressed in releases 4.4.18, 5.0.10 and 6.1.9.
The v3 branch of node-tar has been deprecated and did not receive patches for these issues. If you are
still using a v3 release we recommend you update to a more recent version of node-tar. If this is not
possible, a workaround is available in the referenced GHSA-qq89-hq3f-393p.
CVE-2021-3807:
ansi-regex is vulnerable to Inefficient Regular Expression Complexity
CVE-2021-3918:
json-schema is vulnerable to Improperly Controlled Modification of Object Prototype Attributes ('Prototype
Pollution')
