Design/Logic Flaw

In a Dynamic Host Configuration Protocol version 6 DHCPv6 environment, the jdhcpd daemon may crash and restart upon receipt of certain DHCPv6 solicit messages received from a DHCPv6 client. By continuously sending the same crafted packet, an attacker can repeatedly crash the jdhcpd process causin...

Cisco Application Policy Infrastructure Controller Linux Kernel IP Fragment Reassembly DoS

According to its self-reported version, the Cisco Application Policy Infrastructure Controller APIC is affected by a vulnerability in the IP stack that is used by the Linux Kernel publicly known as FragmentSmack. The vulnerability could allow an unauthenticated, remote attacker to cause a denial ...

IPv6 unmasking via UPnP

Martin Zeiser and Aleksandar Nikolich authored this post. Executive summary With tools such as ZMap and Masscan and general higher bandwidth availability, exhaustive internet-wide scans of full IPv4 address space have become the norm after it was once impractical. Projects like Shodan and Scans.i...

CVE-2019-9162: Out-of-bounds Write

In the Linux kernel before 4.20.12, net/ipv4/netfilter/nfnatsnmpbasicmain.c in the SNMP NAT module has insufficient ASN.1 length checks aka an array index error, making out-of-bounds read and write operations possible, leading to an OOPS or local privilege escalation. This affects snmpversion and...

Debian DLA-1682-1 : uriparser security update

Joergen Ibsen reported an issue with uriparser, a URI parsing library compliant with RFC 3986. An Out-of-bounds read for incomplete URIs with IPv6 addresses with embedded IPv4 address, e.g. '//::44.1', were possible. For Debian 8 'Jessie', this problem has been fixed in version 0.8.0.1-2+deb8u2. ...
