An SRX Series Service Gateway configured for Unified Threat Management UTM may experience a system crash with the error message "mbuf exceed" -- an indication of memory buffer exhaustion -- due to the receipt of crafted HTTP traffic. Each crafted HTTP packet inspected by UTM consumes mbufs which...
CVE-2019-0010
Summary: CVE-2019-0010 affects Juniper SRX Series with Junos OS UTM enabled. Crafted HTTP traffic can exhaust mbufs in SPU/JMPI, causing a system crash (DoS) and failover. The issue is observed when HTTP AV inspection is enabled; WEB Filtering alone is unaffected. Affected products/versions (per ...
FreeBSD : FreeBSD -- Resource exhaustion in IP fragment reassembly (359e1548-a652-11e8-805b-a4badb2f4699)
A researcher has notified us of a DoS attack applicable to another operating system. While FreeBSD may not be vulnerable to that exact attack, we have identified several places where inadequate DoS protection could allow an attacker to consume system resources. It is not necessary that the attack...
