description

NetScaler ADC and NetScaler Gateway are affected by a memory-overflow condition when handling SMPP traffic. Malformed or improperly handled SMPP traffic may cause denial of service or other unpredictable behavior; the affected service must be reachable by an attacker.

mitigation

Upgrade NetScaler ADC to 14.1-73.57, 13.1-64.39, 14.1-73.58 FIPS, or 13.1-37.293 FIPS and NDcPP. 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
