In the jsrsasign package through 10.1.13 for Node.js, some invalid RSA PKCS1 v1.5 signatures are mistakenly recognized to be valid. NOTE: there is no known practical attack...

CVE-2020-36315

In RELIC before 2020-08-01, RSA PKCS1 v1.5 signature forgery can occur because certain checks of the padding and of the first two bytes are inadequate. NOTE: this requires that a low public exponent such as 3 is being used. The product, by default, does not generate RSA keys with such a low numbe...

CVE-2020-36315

Summary: CVE-2020-36315 affects RELIC before 2020-08-01, allowing RSA PKCS#1 v1.5 signature forgery due to inadequate padding checks (and issues with the first two bytes). The vulnerability’s exploitation requires a low public exponent (e.g., 3), and the product defaults to not using such small e...

CVE-2020-36316

CVE-2020-36316 concerns the RELIC cryptographic library. A buffer overflow occurs in PKCS#1 v1.5 signature verification when garbage bytes are present, affecting RELIC prior to 2021-04-03. The connected documents consistently describe this as a RELIC library issue with a pre-2021-04-03 cutoff and...
