If a flow cannot be added (e.g., the flow action is a go-to for a group id that does not exist), OvS tries to revert back all previous flows that were successfully applied from the same bundle. This is possible since OvS maintains list of old flows that were replaced by flows from the bundle. While reinserting old flows, OvS has an assertion failure due to a check on rule state != RULE_INITIALIZED. This would work for new flows, but for an old flow the rule state is RULE_REMOVED. The assertion failure causes an OvS crash. Open vSwitch (OvS) Contains an input validation vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. Open vSwitch is prone to a remote denial-of-service vulnerability. Attackers can exploit this issue to cause a denial-of-service condition, denying service to legitimate users. Open vSwitch 2.7.0 through 2.7.6, 2.8.0 through 2.8.4, and 2.9.0 through 2.9.2 are vulnerable. Open vSwitch (OvS) is a multi-layer virtual switch product based on open source technology (according to the Apache2.0 license). It supports large-scale network automation, standard management interfaces and protocols, etc. through programming extensions. There is a security vulnerability in the 'ofproto_rule_insert__' function of the ofproto/ofproto.c file in OvS 2.7.x to 2.7.6. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: openvswitch security, bug fix, and enhancement update Advisory ID: RHSA-2018:3500-01 Product: Fast Datapath Advisory URL: https://access.redhat.com/errata/RHSA-2018:3500 Issue date: 2018-11-05 CVE Names: CVE-2018-17204 CVE-2018-17205 CVE-2018-17206 ===================================================================== 1.

Software Description: - openvswitch: Ethernet virtual switch Details: It was discovered that Open vSwitch incorrectly decoded certain packets. This issue only affected Ubuntu 18.04 LTS. (CVE-2018-17205) It was discovered that Open vSwitch incorrectly handled BUNDLE action decoding. (CVE-2018-17206) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 18.04 LTS: openvswitch-common 2.9.2-0ubuntu0.18.04.3 Ubuntu 16.04 LTS: openvswitch-common 2.5.5-0ubuntu0.16.04.2 In general, a standard system update will make all the necessary changes

An issue was discovered in Open vSwitch (OvS) 2.7.x through 2.7.6, affecting parse_group_prop_ntr_selection_method in lib/ofp-util.c. When decoding a group mod, it validates the group type and command after the whole group mod has been decoded. The OF1.5 decoder, however, tries to use the type and command earlier, when it might still be invalid. This causes an assertion failure (via OVS_NOT_REACHED). ovs-vswitchd does not enable support for OpenFlow 1.5 by default. Open vSwitch (OvS) Contains an input validation vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. Open vSwitch (OvS) is a multi-layer virtual switch product based on open source technology (according to the Apache2.0 license). It supports large-scale network automation, standard management interfaces and protocols, etc. through programming extensions. There is a security vulnerability in the 'parse_group_prop_ntr_selection_method' function of the lib/ofp-util.c file in OvS 2.7.x to 2.7.6. An attacker can exploit this vulnerability to cause an assertion to fail. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: openvswitch security, bug fix, and enhancement update Advisory ID: RHSA-2018:3500-01 Product: Fast Datapath Advisory URL: https://access.redhat.com/errata/RHSA-2018:3500 Issue date: 2018-11-05 CVE Names: CVE-2018-17204 CVE-2018-17205 CVE-2018-17206 ===================================================================== 1.

The Symantec Messaging Gateway product prior to 10.6.6 may be susceptible to a XML external entity (XXE) exploit, which is a type of issue where XML input containing a reference to an external entity is processed by a weakly configured XML parser. The attack uses file URI schemes or relative paths in the system identifier to access files that should not normally be accessible. Attackers can exploit this issue to gain access to sensitive information or cause denial-of-service conditions. Versions prior to Messaging Gateway 10.6.6 are vulnerable. Symantec Messaging Gateway is a set of anti-spam, anti-virus, advanced content filtering and data leakage prevention technologies developed by Symantec
