Multiple memory overflow vulnerabilities in NetScaler ADC and NetScaler Gateway can lead to unpredictable or erroneous behavior and Denial of Service (DoS). The vulnerability occurs when NetScaler ADC is configured as an Oracle load balancer, DNS proxy, or DNS recursive resolver.

Insufficient input validation in NetScaler ADC and NetScaler Gateway leads to memory overread when the device is configured as a SAML IDP.

The vulnerability allows a DoS attack via malformed HTTP/2 requests to NetScaler ADC and NetScaler Gateway. It occurs when HTTP/2 is enabled in the HTTP profile and associated with a virtual server (LB, CS, VPN) or a service configured on the device.
