CPython 安全漏洞

CPython is a Python interpreter implemented in C language by the Python Foundation. CPython has a security vulnerability that stems from the possibility of objects being reused after decompression errors. If an application catches an OSError and retries with the same decompressor, specially craft...

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...

OESA-2026-2116 python3 security update

Python combines remarkable power with very clear syntax. It has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. There are interfaces to many system calls and libraries, as well as to various windowing systems. New built-in modules are easily written in C or C...

BIT-PYTHON-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...
