DLA-1166-2 tomcat7 -- LTS security update

Date Reported:
10 Nov 2017
Affected Packages:
tomcat7
Vulnerable:
Yes
Security database references:
In the Debian bugtracking system: Bug 881162.
More information:

The update for tomcat7 issued as DLA-1166-1 caused a regressions whereby every request, including for the root document (/), returned HTTP status 404. Updated packages are now available to address this problem. For reference, the original advisory text follows.

When HTTP PUT was enabled (e.g., via setting the readonly initialization parameter of the Default servlet to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

For Debian 7 Wheezy, these problems have been fixed in version 7.0.28-4+deb7u17.

We recommend that you upgrade your tomcat7 packages.
