description

NetScaler ADC and NetScaler Gateway versions before the listed fixed releases are affected by a memory buffer bounds flaw. An unauthenticated remote attacker may disrupt service on a vulnerable network-accessible instance; no user interaction is indicated.

mitigation

Upgrade ADC to 14.1-73.41, 13.1-64.28, 14.1-73.41 FIPS, or 13.1-37.282 as applicable, and upgrade Gateway to 14.1-73.41 or 13.1-64.28. Until upgraded, restrict network access to the management or service interfaces wherever operationally feasible.

fixed in 14.1-73.41, 13.1-64.28, 14.1-73.41 FIPS, 13.1-37.282
