 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-3883-1 [email protected] https://www.debian.org/lts/security/ Chris Lamb September 09, 2024 https://wiki.debian.org/LTS
 - -------------------------------------------------------------------------

 Package : python-jwcrypto Version : 0.8.0-1+deb11u1 CVE ID : CVE-2024-28102 Debian Bug : 1065688

 It was discovered that there was a potential denial of service (DoS) attack in python-jwcrypto, an implementation of JSON Web Encryption and similar object signing standards.

 This could have been exploited by passing python-jwcrypto a malicious JWE token with a high compression ratio. When the server processed said token, it would have consumed a lot of memory and processing time.

 For Debian 11 bullseye, this problem has been fixed in version 0.8.0-1+deb11u1.

 We recommend that you upgrade your python-jwcrypto packages.

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

 Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the python3-jwcrypto packages.
