ASA-2019-00238 – Confluence: Path traversal in the downloadallattachments resource
Confluence Server and Data Center had a path traversal vulnerability in the downloadallattachments resource. A remote attacker who has permission to add attachments to pages and / or blogs, or to create a new space or personal space, or who has 'Admin' permissions for a space, can exploit this path traversal vulnerability to write files to arbitrary locations which can lead to remote code execution on systems that run a vulnerable version of Confluence Server or Data Center.
ASA-2019-00237 – VMware: Vertex shader out-of-bounds read vulnerability
VMware ESXi, Workstation and Fusion updates address an out-of-bounds vulnerability with the vertex shader functionality. Exploitation of this issue requires an attacker to have access to a virtual machine with 3D graphics enabled. Successful exploitation of this issue may lead to information disclosure or may allow attackers with normal user privileges to create a denial-of-service condition on their own VM. The workaround for this issue involves disabling the 3D-acceleration feature. This feature is not enabled by default on ESXi and is enabled by default on Workstation and Fusion.
ASA-2019-00236 – VMware: Out-of-bounds read vulnerability
VMware ESXi, Workstation and Fusion updates address an out-of-bounds read vulnerability. Exploitation of this issue requires an attacker to have access to a virtual machine with 3D graphics enabled. Successful exploitation of this issue may lead to information disclosure.The workaround for this issue involves disabling the 3D-acceleration feature. This feature is not enabled by default on ESXi and is enabled by default on Workstation and Fusion.
ASA-2019-00235 – VMware: Multiple shader translator out-of-bounds read vulnerabilities
VMware ESXi, Workstation and Fusion contain multiple out-of-bounds read vulnerabilities in the shader translator. Exploitation of these issues requires an attacker to have access to a virtual machine with 3D graphics enabled. Successful exploitation of these issues may lead to information disclosure or may allow attackers with normal user privileges to create a denial-of-service condition on their own VM. The workaround for these issues involves disabling the 3D-acceleration feature. This feature is not enabled by default on ESXi and is enabled by default on Workstation and Fusion.
ASA-2019-00234 – BIND: Limiting simultaneous TCP clients is ineffective
By design, BIND is intended to limit the number of TCP clients that can be connected at any given time. The number of allowed connections is a tunable parameter which, if unset, defaults to a conservative value for most servers. Unfortunately, the code which was intended to limit the number of simultaneous connections contains an error which can be exploited to grow the number of simultaneous connections beyond this limit.
ASA-2019-00233 – BIND: Supported Preview Edition can exit with an assertion failure if nxdomain-redirect is used
In BIND Supported Preview Edition, an error in the nxdomain-redirect feature can occur in versions which support EDNS Client Subnet (ECS) features. In those versions which have ECS support, enabling nxdomain-redirect is likely to lead to BIND exiting due to assertion failure.
ASA-2019-00232 – BIND: An error in the nxdomain redirect feature can cause BIND to exit with an INSIST assertion failure in query.c
A programming error in the nxdomain-redirect feature can cause an assertion failure in query.c if the alternate namespace used by nxdomain-redirect is a descendant of a zone that is served locally.The most likely scenario where this might occur is if the server, in addition to performing NXDOMAIN redirection for recursive clients, is also serving a local copy of the root zone or using mirroring to provide the root zone, although other configurations are also possible.
