EulerOS 2.0 SP10 : python-jwt (EulerOS-SA-2022-2434)

high Nessus Plugin ID 165819

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the python-jwt package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - PyJWT is a Python implementation of RFC 7519. PyJWT supports multiple different JWT signing algorithms.
 With JWT, an attacker submitting the JWT token can choose the used signing algorithm. The PyJWT library requires that the application chooses what algorithms are supported. The application can specify `jwt.algorithms.get_default_algorithms()` to get support for all algorithms, or specify a single algorithm. The issue is not that big as `algorithms=jwt.algorithms.get_default_algorithms()` has to be used. Users should upgrade to v2.4.0 to receive a patch for this issue. As a workaround, always be explicit with the algorithms that are accepted and expected when decoding. (CVE-2022-29217)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected python-jwt packages.
