Critical: thunderbird

Issue Overview: When an inner window is reused, it does not consider the use of document.domain for cross-origin protections. If pages on different subdomains ever cooperatively use document.domain, then either page can abuse this to inject script into arbitrary pages on the other subdomain, even...

Amazon Linux AMI : tomcat7 (ALAS-2019-1235)

The SSI printenv command in Apache Tomcat echoes user provided data without escaping and is, therefore, vulnerable to XSS. SSI is disabled by default. The printenv command is intended for debugging and is unlikely to be present in a production website. CVE-2019-0221 C Tenable Network Security, In...

Amazon Linux AMI : python35 (ALAS-2019-1243)

An issue was discovered in urllib2 in Python 2.x and urllib in Python 3.x. CRLF injection is possible if the attacker controls a url parameter, as demonstrated by the first argument to urllib.request.urlopen with \r\n specifically in the query string after a ? character followed by an HTTP header...
