Astra Linux – vulnerability in python2.7, pypy

In Lib/tarfile.py within Python up to version 3.8.3, an attacker can craft a TAR archive that results in an infinite loop when opened by tarfile.open, as procpax fails to validate the header...

GHSA-R292-9MHP-454M node-tar: Uncontrolled recursion in mapHas/filesFilter allows uncatchable stack-overflow DoS via crafted long-path tar with member selection

Summary node-tar npm tar contains an uncontrolled-recursion stack-exhaustion DoS in the internal mapHas helper used by filesFilter. When a consumer calls tar.t... or tar.x... with a non-empty member-selection list, node-tar installs a filter that closes over the recursive mapHas src/list.ts:33-44...

CVE-2026-53655

A flaw was found in node-tar. This vulnerability arises because node-tar incorrectly applies PAX extended header size records to subsequent intermediary metadata headers, leading to a desynchronization of the tar stream cursor compared to other standard tar implementations. A remote attacker coul...

SUSE CVE-2026-53655

node-tar is a full-featured Tar for Node.js. Prior to 7.5.16, tar node-tar applies a PAX extended header's size= record and other PAX overrides to the next header entry of any type, including intermediary metadata headers such as a GNU long-name L or long-link K entry. Per POSIX pax, a PAX extend...

SUSE CVE-2025-62518

astral-tokio-tar is a tar archive reading/writing library for async Rust. Versions of astral-tokio-tar prior to 0.5.6 contain a boundary parsing vulnerability that allows attackers to smuggle additional archive entries by exploiting inconsistent PAX/ustar header handling. When processing archives...

GHSA-W476-P2H3-79G9 uv has differential in tar extraction with PAX headers

Impact In versions 0.9.4 and earlier of uv, tar archives containing PAX headers with file size overrides were not handled properly. As a result, an attacker could contrive a source distribution as a tar archive that would extract differently when installed via uv versus other Python package...

RUSTSEC-2025-0111 `tokio-tar` parses PAX extended headers incorrectly, allows file smuggling

The archive reader incorrectly handles PAX extended headers, when the ustar header incorrectly specifies zero size size=000000000000, while a PAX header specifies a non-zero size, tokio-tar::Archive is going to read the file content as tar entry header. This can be used by a tar file to present...
