The core of Apple is PPL: Breaking the XNU kernel's kernel

Posted by Brandon Azad, Project Zero While doing research for the one-byte exploit technique, I considered several ways it might be possible to bypass Apple's Page Protection Layer PPL using just a physical address mapping primitive, that is, before obtaining kernel read/write or defeating PAC...

CVE-2020-3698

Out of bound write while QoS DSCP mapping due to improper input validation for data received from association response frame in Snapdragon Auto, Snapdragon Compute, Snapdragon Consumer Electronics Connectivity, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile, Snapdragon Voic...

CVE-2020-3698

CVE-2020-3698 describes an out-of-bounds write during QoS DSCP mapping caused by improper input validation of data from an association response frame in Qualcomm-powered Snapdragon platforms (widely listed devices such as APQ8009/SDM66x families and others). The underlying issue affects data hand...

undertow: servletPath is normalized incorrectly leading to dangerous application mapping which could result in security bypass

A flaw was found in Undertow, where the servlet container causes the servletPath to normalize incorrectly by truncating the path after the semicolon. The flaw may lead to application mapping, resulting in a security bypass...

DEBIAN-CVE-2020-15564

An issue was discovered in Xen through 4.13.x, allowing Arm guest OS users to cause a hypervisor crash because of a missing alignment check in VCPUOPregistervcpuinfo. The hypercall VCPUOPregistervcpuinfo is used by a guest to register a shared region with the hypervisor. The region will be mapped...

Kernel: vfio: access to disabled MMIO space of some devices may lead to DoS scenario

A flaw was found in the Linux kernel, where it allows userspace processes, for example, a guest VM, to directly access h/w devices via its VFIO driver modules. The VFIO modules allow users to enable or disable access to the devices' MMIO memory address spaces. If a user attempts to access the...

DEBIAN-CVE-2020-14058

An issue was discovered in Squid before 4.12 and 5.x before 5.0.3. Due to use of a potentially dangerous function, Squid and the default certificate validation helper are vulnerable to a Denial of Service when opening a TLS connection to an attacker-controlled server for HTTPS. This occurs becaus...
