This blog post outlines the work that Microsoft is doing to eliminate uninitialized stack memory vulnerabilities from Windows and why we’re on this path. This blog post will be broken down into a few parts that folks can jump to: Uninitialized Memory Background Potential Solutions to Uninitialized Memory Vulnerabilities InitAll – Automatic Initialization Interesting Findings with InitAll Performance Optimizations Impact for Customers Forward Looking Plans None of this work would have been possible without close partnership between the Visual Studio organization, the Windows organization, and MSRC.

An exploitable out-of-bounds write vulnerability exists in the store_data_buffer function of the igcore19d.dll library of Accusoft ImageGear 19.5.0. A specially crafted PNG file can cause an out-of-bounds write, resulting in a remote code execution. An attacker needs to provide a malformed file to the victim to trigger the vulnerability.

An exploitable out-of-bounds write vulnerability exists in the ico_read function of the igcore19d.dll library of Accusoft ImageGear 19.6.0. A specially crafted ICO file can cause an out-of-bounds write, resulting in a remote code execution. An attacker needs to provide a malformed file to the victim to trigger the vulnerability.

The Azure Sphere Security Research Challenge is an expansion of Azure Security Lab, announced at Black Hat in August 2019. At that time, a select group of talented researchers was invited to come and do their worst, emulating criminal hackers in a customer-safe cloud environment. This new research challenge aims to spark new high impact security research in Azure Sphere, a comprehensive IoT security solution delivering end to end security across hardware, OS and the cloud.

In PHP versions 7.2.x below 7.2.30, 7.3.x below 7.3.17 and 7.4.x below 7.4.5, if PHP is compiled with EBCDIC support (uncommon), urldecode() function can be made to access locations past the allocated memory, due to erroneously using signed numbers as array indexes.
