CVE-2021-3623

libtpms: out-of-bounds access when trying to resume the state of the vTPM

A flaw was found in libtpms. The flaw can be triggered by specially-crafted TPM 2 command packets containing illegal values and may lead to an out-of-bounds access when the volatile state of the TPM 2 is marshalled/written or unmarshalled/read. The highest threat from this vulnerability is to system availability.

hivex: stack overflow due to recursive call of _get_children()

A flaw was found in the hivex library. This flaw allows an attacker to input a specially crafted Windows Registry (hive) file, which would cause hivex to recursively call the _get_children() function, leading to a stack overflow. The highest threat from this vulnerability is to system availability.

Rapid7 Velociraptor Notebooks Authenticated Persistent XSS

Rapid7 Velociraptor 0.5.9 and prior is vulnerable to a post-authentication persistent cross-site scripting (XSS) issue, where an authenticated user could abuse MIME filetype sniffing to embed executable code on a malicious upload. This issue was fixed in version 0.6.0. Note that login rights to Velociraptor is nearly always reserved for trusted and verified users with IT security backgrounds.

ALPACA: Application Layer Protocol Confusion - Analyzing and Mitigating Cracks in TLS Authentication

ALPACA is an application layer protocol content confusion attack, exploiting TLS servers implementing different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A MiTM attacker having access to victim's traffic at the TCP/IP layer can redirect traffic from one subdomain to another, resulting in a valid TLS session. This breaks the authentication of TLS and cross-protocol attacks may be possible where the behavior of one protocol service may compromise the other at the application layer.

QEMU: pvrdma: unchecked malloc size due to integer overflow in init_dev_ring()

An integer overflow was found in the QEMU implementation of VMWare's paravirtual RDMA device in versions prior to 6.1.0. The issue occurs while handling a "PVRDMA_REG_DSRHIGH" write from the guest due to improper input validation. This flaw allows a privileged guest user to make QEMU allocate a large amount of memory, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

Inclusion of Functionality from Untrusted Control Sphere in PHPMailer/PHPMailer

PHPMailer 6.4.1 and earlier contain a vulnerability that can result in untrusted code being called (if such code is injected into the host project's scope by other means). If the $patternselect parameter to validateAddress() is set to 'php' (the default, defined by PHPMailer::$validator), and the global namespace contains a function called php, it will be called in preference to the built-in validator of the same name. Mitigated in PHPMailer 6.5.0 by denying the use of simple strings as validator function names.

buildah: Host environment variables leaked in build container when using chroot isolation

An information disclosure flaw was found in Buildah, when building containers using chroot isolation. Running processes in container builds (e.g. Dockerfile RUN commands) can access environment variables from parent and grandparent processes. When run in a container in a CI/CD environment, environment variables may include sensitive information that was shared with the container in order to be used only by Buildah itself (e.g. container registry credentials).
