 ------------------------------------------------------------------------- Debian LTS Advisory DLA-3811-1 [email protected] https://www.debian.org/lts/security/ Guilhem Moulin May 08, 2024 https://wiki.debian.org/LTS
 -------------------------------------------------------------------------

 Package : python-idna Version : 2.6-1+deb10u1 CVE ID : CVE-2024-3651 Debian Bug : 1069127

 Guido Vranken discovered an issue in python3-idna, a library to support the Internationalized Domain Names in Applications (IDNA) protocol. A specially crafted argument to the idna.encode() function could consume significant resources, which may lead to Denial of Service.

 For Debian 10 buster, this problem has been fixed in version 2.6-1+deb10u1.

 We recommend that you upgrade your python-idna packages.

 For the detailed security status of python-idna please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/python-idna
