Descriptions

latchset jose through version 11 allows attackers to cause a denial of service (CPU consumption) via a large p2c (aka PBES2 Count) value.

Latchset jose hasta la versión 11 permite a los atacantes provocar una denegación de servicio (consumo de CPU) a través de un valor grande de p2c (también conocido como PBES2 Count).

A flaw was found in the Jose package, where a large number of iterations used to derive the wrapping key for the PBKDF2 algorithm may lead to a denial of service. This flaw allows an attacker to set a large number of `PBKDF2' iterations, triggering an uncontrolled resource consumption that impacts the availability of the targeted application.

An update for jose is now available for Red Hat Enterprise Linux 8. Issues addressed include denial of service and resource exhaustion vulnerabilities.
