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.Show less

An information leak vulnerability was found in Undertow. If all headers are not written out in the first write() call then the code that handles flushing the buffer will always write out the full contents of the writevBuffer buffer, which may contain data from previous requests.Show less

A denial of service vulnerability was identified that exists in Apache SpamAssassin before 3.4.2. The vulnerability arises with certain unclosed tags in emails that cause markup to be handled incorrectly leading to scan timeouts. In Apache SpamAssassin, using HTML::Parser, we setup an object and hook into the begin and end tag event handlers In both cases, the "open" event is immediately followed by a "close" event - even if the tag *does not* close in the HTML being parsed. Because of this, we are missing the "text" event to deal with the object normally. This can cause carefully crafted emails that might take more scan time than expected leading to a Denial of Service. The issue is possibly a bug or design decision in HTML::Parser that specifically impacts the way Apache SpamAssassin uses the module with poorly formed html. The exploit has been seen in the wild but not believed to have been purposefully part of a Denial of Service attempt. We are concerned that there may be attempts to abuse the vulnerability in the future.Show less

Tendrl API in Red Hat Gluster Storage before 3.4.0 does not immediately remove session tokens after a user logs out. Session tokens remain active for a few minutes allowing attackers to replay tokens acquired via sniffing/MITM attacks and authenticate as the target user.Show less

It was found that the improper default permissions on /tmp/auth directory in JBoss Enterprise Application Platform before 7.1.0 can allow any local user to connect to CLI and allow the user to execute any arbitrary operations.Show less

A privilege escalation flaw was found in the Ansible Tower. When Tower before 3.0.3 deploys a PostgreSQL database, it incorrectly configures the trust level of postgres user. An attacker could use this vulnerability to gain admin level access to the database.Show less

A flaw was found in the CloudForms API before 5.6.3.0, 5.7.3.1 and 5.8.1.2. A user with permissions to use the MiqReportResults capability within the API could potentially view data from other tenants or groups to which they should not have access.Show less

When using the Linux bridge ml2 driver, non-privileged tenants are able to create and attach ports without specifying an IP address, bypassing IP address validation. A potential denial of service could occur if an IP address, conflicting with existing guests or routers, is then assigned from outside of the allowed allocation pool. Versions of openstack-neutron before 13.0.0.0b2, 12.0.3 and 11.0.5 are vulnerable.Show less

The OpenStack RabbitMQ container image insecurely retrieves the rabbitmq_clusterer component over HTTP during the build stage. This could potentially allow an attacker to serve malicious code to the image builder and install in the resultant container image. Version of openstack-rabbitmq-container and openstack-containers as shipped with Red Hat Openstack 12, 13, 14 are believed to be vulnerable.Show less

An issue was discovered in Artifex Ghostscript before 9.25. Incorrect "restoration of privilege" checking when running out of stack during exception handling could be used by attackers able to supply crafted PostScript to execute code using the "pipe" instruction. This is due to an incomplete fix for CVE-2018-16509.Show less

An information disclosure vulnerability was found in JBoss Enterprise Application Platform before 7.0.4. It was discovered that when configuring RBAC and marking information as sensitive, users with a Monitor role are able to view the sensitive information.Show less

An authorization flaw was found in Pacemaker before 1.1.16, where it did not properly guard its IPC interface. An attacker with an unprivileged account on a Pacemaker node could use this flaw to, for example, force the Local Resource Manager daemon to execute a script as root and thereby gain root access on the machine.Show less
