NVD Description

Note: Versions mentioned in the description apply only to the upstream python313-jwcrypto package and not the python313-jwcrypto package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

A flaw was found in jwcrypto. A remote attacker can send a specially crafted JSON Web Encryption (JWE) token containing numerous period delimiters. This malformed token can force the JWE.deserialize() function to allocate excessive memory, leading to a MemoryError. This issue results in a denial of service (DoS) for services that process untrusted JWE values.
