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...

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...
