CWE
  • CWE-824 - Access of Uninitialized Pointer
  • Denial of Service (DoS)
Summary
An Access of Uninitialized Pointer vulnerability in SIP Application Layer Gateway (ALG) of Juniper Networks Junos OS on SRX Series and MX Series allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). When specific valid SIP packets are received the PFE will crash and restart. This issue affects Juniper Networks Junos OS on SRX Series and MX Series: 20.4 versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R3-S2; 21.2 versions prior to 21.2R3-S2; 21.3 versions prior to 21.3R2-S2, 21.3R3; 21.4 versions prior to 21.4R1-S2, 21.4R2; 22.1 versions prior to 22.1R1-S1, 22.1R2. This issue does not affect Juniper Networks Junos OS versions prior to 20.4R1.
