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...
Improper Handling of Highly Compressed Data (Data Amplification)
Overview io.netty:netty-codec is an event-driven asynchronous network application framework. Affected versions of this package are vulnerable to Improper Handling of Highly Compressed Data Data Amplification in the HttpContentDecompressor and DelegatingDecompressorFrameListener components when th...
Netty: HttpContentDecompressor maxAllocation bypass when Content-Encoding set to br/zstd/snappy leads to decompression bomb DoS
Summary HttpContentDecompressor accepts a maxAllocation parameter to limit decompression buffer size and prevent decompression bomb attacks. This limit is correctly enforced for gzip and deflate encodings via ZlibDecoder, but is silently ignored when the content encoding is br Brotli, zstd, or...

Important: python3.12
Issue Overview: The fix for CVE-2026-0672, which rejected control characters in http.cookies.Morsel, was incomplete. The Morsel.update, |= operator, and unpickling paths were not patched, allowing control characters to bypass input validation. Additionally, BaseCookie.jsoutput lacked the output...
Amazon Linux 2023 : python3, python3-devel, python3-idle (ALAS2023-2026-1618)
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1618 advisory. The fix for CVE-2026-0672, which rejected control characters in http.cookies.Morsel, was incomplete. The Morsel.update, |= operator, and unpickling paths were not patched, allowing control...
Amazon Linux 2023 : python3.14, python3.14-devel, python3.14-freethreading (ALAS2023-2026-1617)
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1617 advisory. When using http.cookies.Morsel, user-controlled cookie values and parameters can allow injecting HTTP headers into messages. Patch rejects all control characters within cookie names, values, a...

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...
