Important: python3.13

Issue Overview: The "tarfile" module would still apply normalization of AREGTYPE \x00 blocks to DIRTYPE, even while processing a multi-block member such as GNUTYPELONGNAME or GNUTYPELONGLINK. This could result in a crafted tar archive being misinterpreted by the tarfile module compared to other...

Important: python3.14

Issue Overview: When using the "tarfile" module with a file opened in "streaming mode" mode="r|" the tarfile module did not properly handle EOF, making archive parsing take exponentially longer. CVE-2026-11972 Affected Packages: python3.14 Issue Correction: Run dnf update python3.14 --releasever...

Important: python3.12

Issue Overview: When using the "configparser" module to write configuration files containing multi-line text values with carriage return characters \r the resulting file could be injected with unexpected keys and values if the attacker controls the written value. CVE-2026-0864 When using the...

CVE-2026-62239

FlashAttention (up to 2.8.3.post1) contains a symlink attack in hopper/setup.py: download_and_copy() extracts NVIDIA toolchain archives without validating symlinks or filtering tar members. A local attacker can plant a predictable symlink in the cache to redirect extracted binaries to a chosen lo...

Arbitrary file write via tar traversal in mlflow

A vulnerability in MLflow's pyfunc extraction process allows for arbitrary file writes due to improper handling of tar archive entries. Specifically, the use of tarfile.extractall without path validation enables crafted tar.gz files containing .. or absolute paths to escape the intended extractio...

PYSEC-2026-2398 BentoML Vulnerable to Arbitrary File Write via Symlink Path Traversal in Tar Extraction

Arbitrary File Write via Symlink Path Traversal in Tar Extraction Summary The safeextracttarfile function validates that each tar member's path is within the destination directory, but for symlink members it only validates the symlink's own path, not the symlink's target. An attacker can create a...
