description

NetScaler ADC and Gateway deployments that use SMPP Load Balancing or Content Switching virtual servers are affected by a memory-overflow flaw. An attacker able to send relevant SMPP traffic may cause service disruption or unstable device behavior.

mitigation

Upgrade NetScaler ADC to 14.1-73.57 or 13.1-64.39; use 14.1-73.58 FIPS or 13.1-37.293 FIPS/NDcPP where applicable. Upgrade NetScaler Gateway to 14.1-73.57 or 13.1-64.39, and restrict exposure to SMPP traffic until upgrades are complete.

fixed in 14.1-73.57, 13.1-64.39, 14.1-73.58 FIPS, 13.1-37.293 FIPs and NDcPP
