Description
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to missing release of memory after effective lifetime error in the Anti-Virus processing. A remote non-authenticated attacker can cause a Denial-of-Service (DoS).
On all SRX platforms with Anti-Virus enabled, if a server sends specific content in the HTTP body of a response to a client request, these packets are queued by Anti-Virus processing in Juniper Buffers (jbufs) which are never released.
When these jbufs are exhausted, the device stops forwarding all transit traffic.
Remediation
Install updates from vendor's website.
