filelock: ReadWriteLock on the hard-link route deletes any directory another user renames onto its .filelock-* link directory name
影響: pip:filelock >= 4.1.0, <= 4.2.0 → 4.2.1 ReadWriteLock and AsyncReadWriteLock (the SQLite-backed reader/writer lock) remove their private .filelock- link directories with shutil.rmtree (a recursive delete) on a remembered path. They do not check that the path still names the directory they created. This happens on the hard-link route (a hard link is a second name for the same file). That route is every connection on macOS since 4.1.1 and any POSIX process without a usable /proc/self/fd (a Linux path that names the process's own open f…
filelock: SoftFileLock stale-break restore follows a swapped-in symbolic link and hard-links a file of the user running the lock into the lock directory
影響: pip:filelock >= 4.1.0, <= 4.2.0 → 4.2.1 When a soft-lock stale break finds that the marker (the lock file at ) it renamed aside was a live one recreated by a successor, the restore branch of break_lock_file() checks the break name with lstat (a check that reads a name without following a symbolic link) and then calls os.link(break_path, lock_file) by name. On CPython 3.12 and later on Linux (and on macOS) that call follows a symbolic link (a file that redirects to another path). A local user (the other user below) who can write a sha…

Electron: Off-screen rendering on macOS trusts GPU-supplied frame geometry
影響: npm:electron < 42.11.6 → 42.11.6, npm:electron >= 43.0.0-alpha.1, < 43.7.3 → 43.7.3, npm:electron >= 44.0.0-alpha.1, < 44.4.3 → 44.4.3, npm:electron >= 45.0.0-alpha.1, < 45.0.0-alpha.9 → 45.0.0-alpha.9 In offscreen rendering mode on macOS, frame data received from the GPU process was not fully validated by the main process. A compromised GPU process could cause the main process to read out-of-bounds memory while producing paint event images, disclosing memory or crashing the app. GHSA-pfmc-3mgc-p6fp covers the same issue on the other capture paths. Apps are only affected if they use offscreen rendering (webPreferences.offscreen) on macOS and an attacker has separately gained code execution in…
Django REST framework: Accept header with many large quoted parameters burns ~19s of CPU per request in content negotiation
影響: pip:djangorestframework < 3.18.2 → 3.18.2 DRF's content negotiation parses each Accept token several times per request and never limits the number of tokens or their total size. Each parse ends up in Django's parse_header_parameters, which takes quadratic time when a quoted parameter value is packed with semicolons. On my machine a single GET with a 780KB Accept header made of 96 such tokens kept one gunicorn worker busy for 18.87 seconds (Django 6.1, djangorestframework 3.18.0, gunicorn 26.0.0, Python 3.13, Docker on macOS). The heade…
