ArchLinux: 201611-22: tomcat6: multiple issues
Summary
- CVE-2016-6816 (information disclosure)
The code that parsed the HTTP request line permitted invalid
characters. This could be exploited, in conjunction with a proxy that
also permitted the invalid characters but with a different
interpretation, to inject data into the HTTP response. By manipulating
the HTTP response, the attacker could poison a web-cache, perform an
XSS attack and/or obtain sensitive information from requests other then
their own.
- CVE-2016-8735 (arbitrary code execution)
The JmxRemoteLifecycleListener was not updated to take account of
Oracle's fix for CVE-2016-3427. Therefore, Tomcat installations using
this listener remained vulnerable to a similar remote code execution
vulnerability.
Resolution
Upgrade to 6.0.48-1.
# pacman -Syu "tomcat6>=6.0.48-1"
The problems have been fixed upstream in version 6.0.48.
