An unauthenticated attacker can cause a denial-of-service to the following products: Ivanti Connect Secure (ICS) in versions prior to 9.1R14.3, 9.1R15.2, 9.1R16.2, and 22.2R4, Ivanti Policy Secure (IPS) in versions prior to 9.1R17 and 22.3R1, and Ivanti Neurons for Zero-Trust Access in versions prior to 22.3R1.
Weakness
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
