           Summary: mod_jk reads beyond buffer boundaries if length of chunk
                    too long in send_body_chunk message
           Product: Tomcat 5
           Version: 5.5.16
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Native:JK
        AssignedTo: tomcat-dev@jakarta.apache.org
        ReportedBy: rpluem@apache.org


The AJP connector of Tomcat 5.5.15 contained a bug that sometimes set a too
long length for the chunks delivered by send_body_chunks AJP messages. This
is fixed meanwhile by http://svn.apache.org/viewcvs.cgi?rev=381505&view=rev.

A bug of this type can cause mod_jk to read beyond buffer boundaries and thus
reveal sensitive memory information to a client. The attached patch against
mod_jk 1.2.15 adds a sanity check to prevent mod_jk from reading beyond
buffer boundaries in such cases. This protects mod_jk against buggy or
malicious AJP servers in the backend.
