NVD Description
Note: Versions mentioned in the description apply only to the upstream strongswan package and not the strongswan package as distributed by Ubuntu.
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.
