description

NetScaler ADC and NetScaler Gateway are affected by a memory-handling flaw in GSLB and geolocation-related functions. An attacker may cause service disruption or unstable behavior; the available evidence does not establish the required access level or deployment preconditions.

mitigation

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

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