CVE-2014-6061 is an authentication-related flaw in the Symfony HttpFoundation component affecting applications that rely on HTTP Basic or Digest authentication. The vulnerability stems from improper parsing of the HTTP Authorization header by HttpFoundation in certain server configurations. As a result, authentication handling may be performed incorrectly when the framework processes malformed or ambiguously parsed Authorization header data. Based on the provided advisory, the issue was fixed in Symfony versions 2.3.19, 2.4.9, and 2.5.4, with a corresponding patch published in Symfony pull request #11829.
