Synopsis :

The web application running on the remote web server is affected by a
denial of service vulnerability.

Description :

The version of Cisco Security Manager running on the remote web server
is 4.9.x prior to 4.9(0.397) or 4.10.x prior to 4.10(0.189). It is,
therefore, affected by a NULL pointer dereference flaw in file
rsa_ameth.c due to improper handling of ASN.1 signatures that are
missing the PSS parameter. A remote attacker can exploit this to cause
the signature verification routine to crash, resulting in a denial of
service condition.
