This issue is embargoed until probably Tue 27th Feb (it may well be Wed). Please do not release anything until you see an update publically on the Tomcat site (tomcat.apache.org). -- VULNERABILITY DETAILS ----------------------------------------------- This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apache Tomcat Connector. Authentication is not required to exploit this vulnerability. The specific flaw exists in the URI handler for the mod_jk.so library. When parsing a long URL request, the URI worker map routine performs an unsafe memory copy. This results in a stack overflow condition which can be leveraged execute arbitrary code. The vulnerable routine exists in native/common/jk_uri_worker_map.c: [...] char url[JK_MAX_URI_LEN+1]; [...] for (i = 0; i < strlen(uri); i++) if (uri[i] == ';') break; else url[i] = uri[i]; // Overflow if length(uri) > 4095 url[i] = '\0'; [...] This is the commit that added the flaw: http://svn.apache.org/viewvc/tomcat/connectors/trunk/jk/native/common/jk_uri_worker_map.c?view=diff&r1=424095&r2=424096 Patch from Tomcat security team attached. -- VERSIONS ------------------------------------------------------------ Please note this issue only affected versions 1.2.19 and 1.2.20 of the Apache Tomcat JK Web Server Connector and not previous versions. Tomcat 5.5.20 and Tomcat 4.1.34 included a vulnerable version in their source packages. Other versions of Tomcat were not affected.
