Описание
Versions of the package jsrsasign before 11.1.1 are vulnerable to Infinite loop via the bnModInverse function in ext/jsbn2.js when the BigInteger.modInverse implementation receives zero or negative inputs, allowing an attacker to hang the process permanently by supplying such crafted values (e.g., modInverse(0, m) or modInverse(-1, m)).
A flaw was found in jsrsasign. A remote attacker could exploit this vulnerability by providing specially crafted zero or negative inputs to the bnModInverse function within the BigInteger.modInverse implementation. This could lead to an infinite loop, causing a permanent denial of service (DoS) by hanging the process.
Отчет
IMPORTANT: A denial of service flaw was found in jsrsasign. This vulnerability allows a remote attacker to cause a permanent denial of service by providing specially crafted zero or negative inputs to the bnModInverse function, leading to an infinite loop. This affects Red Hat Migration Toolkit for Virtualization and Red Hat Quay, which utilize the vulnerable jsrsasign component.
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.
