There is no fixed version for org.webjars.bower:jsrsasign.
Overview
org.webjars.bower:jsrsasign is a free pure JavaScript cryptographic library.
Affected versions of this package are vulnerable to Signature Bypass. It allows a malleability in ECDSA signatures by not checking overflows in the length of a sequence and '0' characters appended or prepended to an integer. The modified signatures are verified as valid. This could have a security-relevant impact if an application relied on a single canonical signature.
