BabelDOC: Arbitrary Code Execution via CMap Pickle Deserialization in babeldoc/pdfminer/cmapdb.py
Arbitrary Code Execution via CMap Pickle Deserialization in babeldoc/pdfminer/cmapdb.py Summary BabelDOC's vendored PDF parser babeldoc/pdfminer/cmapdb.py deserializes untrusted pickle data when loading CMap files. The loaddata method strips only NUL bytes from a PDF-controlled CMap name, then...
BIT-PYTHON-MIN-2026-6100 Use-after-free in lzma.LZMADecompressor, bz2.BZ2Decompressor, and gzip.GzipFile after re-use under memory pressure
Use-after-free UAF was possible in the lzma.LZMADecompressor, bz2.BZ2Decompressor, and gzip.GzipFile when a memory allocation fails with a MemoryError and the decompression instance is re-used. This scenario can be triggered if the process is under memory pressure. The fix cleans up the dangling...

python: Python: Arbitrary code execution or information disclosure via use-after-free in decompression modules
A flaw was found in Python's decompression modules, including lzma.LZMADecompressor, bz2.BZ2Decompressor, and gzip.GzipFile. This vulnerability, a use-after-free, can occur if a program attempts to re-use a decompression object after a memory allocation error, especially when the system is...

The vulnerabilities of the functions lzma.LZMADecompressor(), bz2.BZ2Decompressor(), and gzip.GzipFile() in the Python programming language (CPython) allow a malicious actor to trigger a service denial.
The vulnerability of the bytes.decode function in the CPython interpreter relates to the use of memory after it is freed. Exploiting this vulnerability could allow a remote attacker to cause a service failure...

FreeBSD : Python -- use-after-free vulnerability in decompressors under memory pressure (b8e9f33c-375d-11f1-a119-e36228bfe7d4)
The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the b8e9f33c-375d-11f1-a119-e36228bfe7d4 advisory. Seth Larson reports: There is a CRITICAL severity vulnerability affecting CPython. Use-after-free UAF w...

CVE-2026-6100
CVE-2026-6100 affects Python’s decompression modules: at least the in-process reuse of decompressor instances in lzma.LZMADecompressor , bz2.BZ2Decompressor , and gzip.GzipFile can lead to a Use-After-Free (UAF) if a memory allocation fails with a MemoryError and the decompressor is reused. The i...
