Описание
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.
Отчет
This moderate impact flaw in the jwcrypto library can lead to a denial of service in Red Hat products that process untrusted JSON Web Encryption (JWE) values. An attacker could provide a specially crafted malformed JWE token, causing excessive memory allocation and potentially degrading service availability.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
