Summary Boxlite is a sandbox service that allows users to create lightweight virtual machines Boxes and run OCI containers within them. Boxlite allows users to specify the OCI image used by containers in the sandbox. However, when processing tar entries in OCI images, Boxlite does not account for...

CVE-2026-46483

A flaw was found in Vim. When decompressing .tgz archives, the Vimuntar function builds shell commands using shellescape without the special flag. This allows a specially crafted archive filename to trigger Vim cmdline-special expansion and execute arbitrary commands in the context of the current...

golang: archive/tar: Unbounded allocation when parsing GNU sparse map

A flaw was found in the archive/tar package in the Go standard library. tar.Reader does not set a maximum size on the number of sparse region data blocks in GNU tar pax 1.0 sparse files. A specially crafted tar archive with a pax header indicating a big number of sparse regions can cause a Go...

Astra Linux – Vulnerability in php-pear

In ArchiveTar before version 1.4.14, symlinks can reference targets outside of the extracted archive. This is a separate vulnerability from CVE-2020-36193...

Astra Linux – Vulnerability in node-tar

The npm package “tar” also known as node-tar in versions prior to 4.4.16, 5.0.8, and 6.1.7 has vulnerabilities related to arbitrary file creation/overwriting and arbitrary code execution. node-tar aims to ensure that any file whose location would be modified by a symbolic link is not extracted...

Astra Linux – Vulnerability in python-pip

When extracting a tar archive, pip may not check symbolic links pointing into the extraction directory if the tarfile module does not implement PEP 706. Note that upgrading pip to a “fixed” version does not fix all vulnerabilities that are mitigated by using a Python version that implements PEP...

Astra Linux – Vulnerability in tar

In the sparse.c file of GNU Tar, before version 1.32, there was a NULL pointer dereferencing issue when parsing certain archives that contained malformed extended headers...

Astra Linux – Vulnerability in tar

In GNU tar before version 1.35, mishandling of extension attributes in a PAX archive can cause the application to crash in xheader.c...

Astra Linux – Vulnerability in node-tar

The npm package “tar” also known as node-tar in versions 6.1.1, 5.0.6, 4.4.14, and 3.3.2 has an arbitrary File Creation/Overwrite vulnerability due to insufficient absolute path sanitization. node-tar aims to prevent the extraction of absolute file paths by converting absolute paths into relative...

Astra Linux – Vulnerability in tar

A flaw was discovered in the src/list.c file of tar 1.33 and earlier. This flaw allows an attacker who can submit a crafted input file to tar to cause uncontrolled consumption of memory. The greatest threat posed by this vulnerability is to system availability...

Astra Linux – Vulnerability in libtar

An attacker who submits a crafted tar file with a size of 0 in the header struct field may be able to trigger a call to malloc0 for the variable gnulongname, resulting in an out-of-bounds read...

Astra Linux – Vulnerability in Cpio

In all versions of cpio before 2.13, input files are not properly validated when generating TAR archives. When cpio is used to create TAR archives from paths that attackers can access, the resulting archive may contain files with permissions that the attacker does not have, or in paths to which t...

Amazon Linux 2023 : ecs-init (ALAS2023-2026-1637)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1637 advisory. Arithmetic over induction variables in loops were not correctly checked for underflow or overflow in the Go compiler cmd/compile. As a result, the compiler would allow for invalid indexing to...

node-tar: tar: node-tar: Arbitrary file overwrite via Unicode path collision race condition

A flaw was found in node-tar, a library for Node.js. This race condition vulnerability occurs due to incomplete handling of Unicode path collisions within the path-reservations system on case-insensitive filesystems, such as macOS APFS. A remote attacker can exploit this by providing a specially...

node-tar: tar: node-tar: Arbitrary file creation via path traversal bypass in hardlink security check

A flaw was found in node-tar, a Node.js module for handling TAR archives. This vulnerability allows a remote attacker to bypass path traversal protections by crafting a malicious TAR archive. The security check for hardlink entries uses different path resolution logic than the actual hardlink...

node-tar: tar: node-tar: Arbitrary file overwrite and symlink poisoning via unsanitized linkpaths in archives

A flaw was found in the node-tar library. This vulnerability allows an attacker to craft malicious archives that, when extracted, can bypass intended security restrictions. This leads to arbitrary file overwrite and symlink poisoning, potentially allowing unauthorized modification of files on the...
