Updated
gost builds a local copy of Security Tracker(Redhat/Debian/Microsoft).
After you register CVEs to watch list, gost notify via E-mail/Slack if there is an update.
The pronunciation of gost is the same as the English word "ghost".
gost is written in Go, and therefore you can just grab the binary releases and drop it in your $PATH.
gost builds a local copy of Security Tracker (Redhat or Debian or Microsoft).
A system administrator always monitor Security Tracker. It can be a burden. For example, after the vulnerability is found, we have to wait until the patch comes out. I hope anyone notifies me if there is an update.
gost has the following features.
- Build a local copy of Security Tracker
- A server mode for easy querying
- Register CVEs to watch list
- Notify if there is an update (E-Mail or Slack)
- Monitoring metric can be specified (e.g. CVSS Score, Severity, etc.)

"ID": 8452,
"CveID": "CVE-2013-0340",
"Scope": "remote",
"Description": "expat 2.1.0 and earlier does not properly handle entities expansion unless an application developer uses the XML_SetEntityDeclHandler function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because expat already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed, and each affected application would need its own CVE.",
