Description:
* SECURITY UPDATE: tarfile.data_filter could be bypassed using crafted
link entries, including symlinks with empty or directory-like names,
to redirect later archive members outside the intended extraction
directory, so tarfile.extractall() could write files outside the
destination directory.
- debian/patches/CVE-2026-7774.patch: backport of cpython c063191c
([3.10] branch variant of 57841198, gh-149486). data_filter now
validates the normalised link target that is actually written to
disk, resolves a symlink's target relative to its member name with
trailing separators stripped, and rejects link members that would
replace the destination directory itself.
- CVE-2026-7774
* SECURITY UPDATE: ftplib.ftpcp() still called parse227() directly and
passed the source server's self-reported PASV IPv4 address to the
target server's PORT command, so a malicious source FTP server could
redirect the target's data connection to an arbitrary host:port
(SSRF); the CVE-2021-4189 fix only covered FTP.makepasv().
- debian/patches/CVE-2026-8328.patch: backport of cpython eac4fe3b
(gh-87451). ftpcp() now uses the source server's actual peer
address unless trust_server_pasv_ipv4_address is set, the same
rule FTP.makepasv() already applies.
- CVE-2026-8328
