What it is about

Python ist eine universelle, üblicherweise interpretierte, höhere Programmiersprache. Ein entfernter, authentisierter Angreifer kann eine Schwachstelle in Python ausnutzen, um einen Denial of Service Angriff durchzuführen.

Under what conditions?

Over the network, but only with valid access (login required), for example with stolen credentials or as an insider.

What can happen in the worst case

An attacker could use the vulnerability to

  • einen Denial of Service Angriff durchzuführen

Am I affected?

Affected according to the BSI:

  • Debian Linux
  • Amazon Linux 2
  • Red Hat Enterprise Linux
  • Fedora Linux
  • Ubuntu Linux
  • SUSE Linux
  • Oracle Linux
  • SUSE openSUSE
  • RESF Rocky Linux
  • Dell Avamar
  • Open Source Python CPython <3.14.0b3
  • Dell NetWorker Virtual Edition

and 1 more

The installed version is usually shown under “Help → About” or in the device’s admin interface.

What helps?

Update to at least:

  • Open Source Python CPython 3.14.0b3
  • Dell Secure Connect Gateway Appliance 5.32.00.18

Is the vulnerability already being exploited?

None of the CVEs is in the CISA catalogue of exploited vulnerabilities. That does not mean there are no attacks, only that none are documented.
