CVE-2020-14310

There is an issue on grub2 before version 2.06 at function read_section_as_string(). It expects a font name to be at max UINT32_MAX – 1 length in bytes but it doesn’t verify it before proceed with buffer allocation to read the value from the font value. An attacker may leverage that by crafting a malicious font file which has a name with UINT32_MAX, leading to read_section_as_string() to an arithmetic overflow, zero-sized allocation and further heap-based buffer overflow.

CVE-2020-14311

There is an issue with grub2 before version 2.06 while handling symlink on ext filesystems. A filesystem containing a symbolic link with an inode size of UINT32_MAX causes an arithmetic overflow leading to a zero-sized memory allocation with subsequent heap-based buffer overflow.

CVE-2020-5413

Spring Integration framework provides Kryo Codec implementations as an alternative for Java (de)serialization. When Kryo is configured with default options, all unregistered classes are resolved on demand. This leads to the “deserialization gadgets” exploit when provided data contains malicious code for execution during deserialization. In order to protect against this type of attack, Kryo can be configured to require a set of trusted classes for (de)serialization. Spring Integration should be proactive against blocking unknown “deserialization gadgets” when configuring Kryo in code.

CVE-2020-5414

VMware Tanzu Application Service for VMs (2.7.x versions prior to 2.7.19, 2.8.x versions prior to 2.8.13, and 2.9.x versions prior to 2.9.7) contains an App Autoscaler that logs the UAA admin password. This credential is redacted on VMware Tanzu Operations Manager; however, the unredacted logs are available to authenticated users of the BOSH Director. This credential would grant administrative privileges to a malicious user. The same versions of App Autoscaler also log the App Autoscaler Broker password. Prior to newer versions of Operations Manager, this credential was not redacted from logs. This credential allows a malicious user to create, delete, and modify App Autoscaler services instances. Operations Manager started redacting this credential from logs as of its versions 2.7.15, 2.8.6, and 2.9.1. Note that these logs are typically only visible to foundation administrators and operators.

CVE-2019-11286

VMware GemFire versions prior to 9.10.0, 9.9.1, 9.8.5, and 9.7.5, and VMware Tanzu GemFire for VMs versions prior to 1.11.0, 1.10.1, 1.9.2, and 1.8.2, contain a JMX service available to the network which does not properly restrict input. A remote authenticated malicious user may request against the service with a crafted set of credentials leading to remote code execution.

CVE-2020-5396

VMware GemFire versions prior to 9.10.0, 9.9.2, 9.8.7, and 9.7.6, and VMware Tanzu GemFire for VMs versions prior to 1.11.1 and 1.10.2, when deployed without a SecurityManager, contain a JMX service available which contains an insecure default configuration. This allows a malicious user to create an MLet mbean leading to remote code execution.
