jsrsasign is vulnerable to Denial of Service (DoS)
50
Medium Risk
This Affects:
jsrsasignTL;DR
Affected versions of this package are vulnerable to denial of service (DoS) due to an infinite loop in the ASN.1 parsing logic. The ASN1HEX.getChildIdx function processes attacker-controlled input without properly validating value lengths, which can cause the parser to enter a non-terminating loop when handling malformed ASN.1 structures. An attacker able to supply crafted input can trigger excessive CPU consumption, leading to application hang or service disruption.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.

jsrsasign is vulnerable to Denial of Service (DoS) in versions 6.1.2 - 11.1.1.
