This update for python311 fixes the following issues: - CVE-2026-15310: memory exhaustion in zipfile in bzip2/LZMA/Zstandard decompression (bsc#1277111). - CVE-2026-15806: urllib.request.HTTPPasswordMgr credentials for one URL scheme sent over another scheme (bsc#1276223). - CVE-2026-17084: StringPrep algorithm considered Unicode codepoint attributes outside Unicode 3.2.0 (bsc#1276226). - CVE-2026-19445: reassigned SNI callbacks with unreferenced SSLContext instances can cause use-after-free (bsc#1283969). - CVE-2026-19553: omitted server_hostname arguments in wrap_bio() can cause silent hostname verification bypasses (bsc#1283826). - CVE-2026-19672: tarfile extraction filter bypass allows creation of directories outside the destination (bsc#1276227). - CVE-2026-82049: tarfile extraction filters mishandle archives containing a hard link to a symbolic link, allowing file modification and content disclosure (bsc#1280459). Changes for python311: - Update to 3.11.17: - Library - gh-156002: zipfile again reads members through a third-party decompressor installed by monkey-patching the private _get_decompressor() to return an object that only implements old BZ2Decompressor API from Python 3.3. Note that decompressors without needs_input and two-argument decompress() are vulnerable to CVE 2026-15310. - gh-156353: Fix configparser parsing when using whitespace in delimiters. - Build - gh-155757: Set the --argv0 argument to wasmtime for WASI builds so the test suite passes. Otherwise the calculated paths to the stdlib for frozen modules is incorrect.
