description

Affected NetScaler ADC and Gateway releases contain a memory-overflow flaw in SAML processing. An attacker may execute code or disrupt service when the appliance is configured as a SAML service provider or identity provider; the affected SAML role varies by release.

mitigation

Upgrade ADC and Gateway to 14.1-73.46 or 13.1-64.29. For ADC FIPS, install 14.1-73.46 FIPS or 13.1.37.283 FIPS; disable SAML SP and IdP roles where feasible until updates are applied.

fixed in 14.1-73.46, 13.1-64.29, 14.1-73.46 FIPS, 13.1.37.283 FIPS
