NVD reports: Xiph.Org libvorbis 1.3.5 allows Remote Code Execution upon freeing uninitialized memory in the function vorbisanalysisheaderout in info.c when vi-channels=0, a similar issue to Mozilla bug 550184. In Xiph.Org libvorbis 1.3.5, an out-of-bounds array read vulnerability exists in the...

Node.js third-party modules: `njwt` allocates uninitialized Buffers when number is passed in base64urlEncode input

I would like to report an uninitialized Buffer allocation issue in njwt. It allows to extract sensitive data from uninitialized memory or to cause a DoS by passing in a large number, in setups where typed user input can be passed e.g. from JSON. Module module name: njwt version: 0.4.0 npm page:...

Node.js third-party modules: `base64url` allocates uninitialized Buffers when number is passed in input on Node.js 4.x and below

I would like to report an uninitialized Buffer allocation issue in base64url. It allows to extract sensitive data from uninitialized memory or to cause a DoS by passing in a large number, in setups where typed user input can be passed e.g. from JSON, on Node.js 4.x and lower.

Node.js third-party modules: `npmconf` (and `npm` js api) allocate and write to disk uninitialized memory content when a typed number is passed as input on Node.js 4.x

I would like to report a Buffer allocation issue in npmconf and npm package js api. It allows to extract sensitive content from uninitialized memory by passing typed input to setCredentialsByURI, limited to Node.js 4.x and below. Module module name: npmconf version: 2.1.2 npm page:...

Node.js third-party modules: `memjs` allocates and stores buffers on typed input, resulting in DoS and uninitialized memory usage

I would like to report a Buffer allocation vulnerability in memjs. In cases when the attacker is able to pass typed input e.g. via JSON to the storage, it allows to cause DoS on all Node.js versions and to store and potentially later extract chunks of uninitialized server memory containing...

Windows Kernel 64-bit stack memory disclosure in win32k!SfnINLPHELPINFOSTRUCT (via user-mode callback)(CVE-2018-0810)

We have discovered that a user-mode callback invoked by the win32k!SfnINLPHELPINFOSTRUCT function via KeUserModeCallback leads to the disclosure of uninitialized stack memory to user-mode clients, due to compiler-introduced structure padding. The vulnerability affects Windows 7 64-bit; other...
