Uh oh!
There was an error while loading. Please reload this page.
The Tools/ssl/multissltests.py script may extract a possibly untrusted tarball.
Since the script does not necessarily use Python 3.14 or later (where the "data"
filter became the default tarfile extraction filter), the user may theoretically
suffer from a path traversal attack.
Although the script should not be used in production and usually relies on downloading
trusted sources, the "data" extraction filter is now explicitly used wherever relevant.
(cherry picked from commit 31d3836)
