CVE-2018-6459
The rsa_pss_params_parse function in libstrongswan/credentials/keys/signature_params.c in strongSwan 5.6.1 allows remote attackers to cause a denial of service via a crafted RSASSA-PSS signature that lacks a mask generation function parameter.
Does this matter?
Lower severity and a low EPSS score (1.05%). Track it; it rarely justifies an emergency change on its own.
