CWE-908

An integer overflow vulnerability in the Skia library when allocating memory for edge builders on some systems with at least 8 GB of RAM. This results in the use of uninitialized memory, resulting in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58.

An exploitable kernel memory disclosure vulnerability exists in the 0x8200E804 IOCTL handler functionality of WIBU-SYSTEMS WibuKey.sys Version 6.40 (Build 2400).A specially crafted IRP request can cause the driver to return uninitialized memory, resulting in kernel memory disclosure. An attacker can send an IRP request to trigger this vulnerability.

An exploitable memory disclosure vulnerability exists in the 0x222000 IOCTL handler functionality of Sophos HitmanPro.Alert 3.7.6.744. A specially crafted IRP request can cause the driver to return uninitialized memory, resulting in kernel memory disclosure. An attacker can send an IRP request to trigger this vulnerability.

An exploitable uninitialized variable vulnerability exists in the RTF-parsing functionality of Atlantis Word Processor 3.2.6 version. A specially crafted RTF file can leverage an uninitialized stack address, resulting in an out-of-bounds write, which in turn could lead to code execution.

A use of uninitialized value was found in libwebp in versions before 1.0.1 in ReadSymbol().

An issue was discovered in the smallvec crate before 0.6.13 for Rust. It can create an uninitialized value of any type, including a reference type.
