tar: tar: --one-top-level hardlink targets not confined to top-level directory enabling arbitrary file overwrite
A flaw was found in GNU tar. When extracting an archive with the --one-top-level option, hardlink targets are not confined to the designated top-level directory and may resolve relative to the extraction working directory. A crafted archive can create hardlinks that escape the intended boundary...
CVE-2026-86805 AT_SECURE programs may load attacker-controlled code via $ORIGIN
A time-of-check to time-of-use TOCTOU race condition in the dynamic loader ld.so of the GNU C Library glibc versions 2.14 through 2.44 allows a local attacker to escalate privileges. When expanding $ORIGIN in DTRPATH for setuid/setgid ATSECURE programs, glibc validates the lexically normalized...
CVE-2026-47699
A flaw was found in guest-components. This vulnerability allows an attacker to achieve container escape and gain unauthorized access to the underlying pod virtual machine. When unpacking a crafted Open Container Initiative OCI image layer, the archive extraction routine fails to restrict hard lin...

BIT-PYTHON-MIN-2026-87910 tarfile hardlink fallback ignores custom extraction filter rejection via None
When tarfile extracts a link on a system that doesn't support links, it falls back to extracting a member from the archive. In this case, the filter function is run twice: once for the extracted member, and once with name set to the location of the link. For one of the calls, the return value was...

Astra Linux – Vulnerability in busybox
A flaw was discovered in BusyBox. This vulnerability allows an attacker to modify files outside of the intended extraction directory by creating a malicious tar archive containing unvalidated hardlink or symlink entries. If the tar archive is extracted with elevated privileges, this flaw can lead...
Astra Linux – Vulnerability in node-tar
node-tar is a fully featured Tar library for Node.js. When using default options in versions 7.5.7 and below, an attacker-controlled archive can create a hardlink within the extraction directory that points to a file outside of the extraction root. This allows arbitrary file reading and writing b...
