Descriptions

A flaw was found in the c-ares package. The ares_set_sortlist is missing checks about the validity of the input string, which allows a possible arbitrary length stack overflow. This issue may cause a denial of service or a limited impact on confidentiality and integrity.

Node.js is a software development platform for building fast and scalable network applications in the JavaScript programming language. The package has been upgraded to a later upstream version: nodejs. Issues addressed include HTTP request smuggling, buffer overflow, bypass, crlf injection, and denial of service vulnerabilities.
