CVSS: 5.5EPSS: 0%CPEs: 3EXPL: 1CVE-2022-48303 – tar: heap buffer overflow at from_header() in list.c via specially crafted checksum
https://notcve.org/view.php?id=CVE-2022-48303
GNU Tar through 1.34 has a one-byte out-of-bounds read that results in use of uninitialized memory for a conditional jump. Exploitation to change the flow of control has not been demonstrated. The issue occurs in from_header in list.c via a V7 archive in which mtime has approximately 11 whitespace characters. A flaw was found in the Tar package. When attempting to read files with old V7 tar format with a specially crafted checksum, an invalid memory read may occur. • https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CRY7VEL4AIG3GLIEVCTOXRZNSVYDYYUD https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/X5VQYCO52Z7GAVCLRYUITN7KXHLRZQS4 https://savannah.gnu.org/bugs/?62387 https://savannah.gnu.org/patch/?10307 https://access.redhat.com/security/cve/CVE-2022-48303 https://bugzilla.redhat.com/show_bug.cgi?id=2149722 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •
CVSS: 8.6EPSS: 0%CPEs: 7EXPL: 0CVE-2021-37713 – Arbitrary File Creation/Overwrite on Windows via insufficient relative path sanitization
https://notcve.org/view.php?id=CVE-2021-37713
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 outside of the extraction target directory is not extracted. This is, in part, accomplished by sanitizing absolute paths of entries within the archive, skipping archive entries that contain `..` path portions, and resolving the sanitized paths against the extraction target directory. This logic was insufficient 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, such as `C:some\path`. If the drive letter does not match the extraction target, for example `D:\extraction\dir`, then the result of `path.resolve(extractionDirectory, entryPath)` would resolve against the current working directory on the `C:` drive, rather than the extraction target directory. Additionally, a `..` portion of the path could occur immediately after the drive letter, such as `C:.. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://github.com/npm/node-tar/security/advisories/GHSA-5955-9wpr-37jh https://www.npmjs.com/package/tar https://www.oracle.com/security-alerts/cpuoct2021.html • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 8.6EPSS: 0%CPEs: 8EXPL: 0CVE-2021-37701 – Arbitrary File Creation/Overwrite via insufficient symlink protection due to directory cache poisoning using symbolic links
https://notcve.org/view.php?id=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. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://github.com/npm/node-tar/security/advisories/GHSA-9r2w-394v-53qc https://lists.debian.org/debian-lts-announce/2022/12/msg00023.html https://www.debian.org/security/2021/dsa-5008 https://www.npmjs.com/package/tar https://www.oracle.com/security-alerts/cpuoct2021.html https://access.redhat.com/security/cve/CVE-2021-37701 https://bugzilla.redhat.com/show_bug.cgi?id=1999731 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-59: Improper Link Resolution Before File Access ('Link Following') •
