Titel:	Juniper Networks Junos OS SIP ALG Denial of Service Vulnerability
Zusammenfassung:	DoS on SRX devices when SIP ALG is enabled
Beschreibung:	Summary: DoS on SRX devices when SIP ALG is enabled Vulnerability Insight: On SRX Series devices, when SIP ALG is enabled, a certain crafted SIP packet may cause the flowd process to crash. SIP ALG is enabled by default on SRX Series devices except for SRX-HE devices. SRX-HE devices have SIP ALG disabled by default. The status of ALGs can beobtained by executing the 'show security alg status' CLI command. Vulnerability Impact: Repeated crashes of the flowd process constitutes an extended denial of service condition for the SRX Series device. Affected Software/OS: Junos OS 12.1X46 and 12.1X47 Solution: New builds of Junos OS software are available from Juniper. As a workaround disable SIP ALG or enable flow-based processing for IPv6 traffic. CVSS Score: 7.8 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:C
