EPSS 2.01%
Description
https-proxy-agent before 2.1.1 passes auth option to the Buffer constructor without proper sanitization, resulting in DoS and uninitialized memory leak in setups where an attacker could submit typed input to the 'auth' parameter (e.g. JSON).

Remediation
Red Hat statement
This issue did not affect the versions of nodejs as shipped with Red Hat Enterprise Linux 8 as they already include the patched code. This issue did not affect the versions of rh-nodejs10-nodejs as shipped with Red Hat Software Collections 3 as they already include the patched code. Red Hat Quay uses nodejs-https-proxy-agent, but only as a development dependency, it is not used at runtime. Therefore we rated this issue as having a low impact for Red Hat Quay.
