  "title": "squid: Squid is a caching proxy for the Web",
  "description": "Squid is a caching proxy for the Web. Due to an Improper Validation ofSpecified Index bug, Squid versions 3.3.0.1 through 5.9 and 6.0 prior to6.4 compiled using \u0060--with-openssl\u0060 are vulnerable to a Denial of Serviceattack against SSL Certificate validation. This problem allows a remoteserver to perform Denial of Service against Squid Proxy by initiating a TLSHandshake with a specially crafted SSL Certificate in a server certificatechain. This attack is limited to HTTPS and SSL-Bump. This bug is fixed inSquid version 6.4. In addition, patches addressing this problem for thestable releases can be found in Squid\u0027s patch archives. Those who you use aprepackaged version of Squid should refer to the package vendor foravailability information on updated packages.",
