golang.org/x/crypto before v0.0.0-20200220183623-bac4c82f6975 for Go allows a panic during signature verification in the golang.org/x/crypto/ssh package. A client can attack an SSH server that accepts public keys. Also, a server can attack any SSH client.

Prototype Pollution in lodash
Versions of lodash prior to 4.17.19 are vulnerable to Prototype Pollution. The functions `pick`, `set`, `setWith`, `update`, `updateWith`, and `zipObjectDeep` allow a malicious user to modify the prototype of Object if the property identifiers are user-supplied. Being affected by this issue requires manipulating objects based on user-provided property values or arrays.

This vulnerability causes the addition or modification of an existing property that will exist on all objects and may lead to Denial of Service or Code Execution under specific circumstances.

Potential XSS vulnerability in jQuery
### Impact
Passing HTML containing `<option>` elements from untrusted sources - even after sanitizing them - to one of jQuery's DOM manipulation methods (i.e. `.html()`, `.append()`, and others) may execute untrusted code.

### Patches
This problem is patched in jQuery 3.5.0.

### Workarounds
To workaround this issue without upgrading, use [DOMPurify](https://github.com/cure53/DOMPurify) with its `SAFE_FOR_JQUERY` option to sanitize the HTML string before passing it to a jQuery method.
