Developer News: Apache 1.3.27 Launched!

Posted by: w4z004on 2002/10/4 14:07:06 5844 reads There is a new Apache released and this time its version 1.3.27. Security vulnerabilities The main security vulnerabilities addressed in 1.3.27 are:

- Fix the security vulnerability noted in CAN-2002-0839 (cve.mitre.org) regarding ownership permissions of System V shared memory based scoreboards. The fix resulted in the new ShmemUIDisUser directive. - Fix the security vulnerability noted in CAN-2002-0840 (cve.mitre.org) regarding a cross-site scripting vulnerability in the default error page when using wildcard DNS. - Fix the security vulnerability noted in CAN-2002-0843 (cve.mitre.org) regarding some possible overflows in ab.c which could be exploited by a malicious server. New features The main new features in 1.3.27 (compared to 1.3.26) are: - The new ErrorHeader directive has been added. - Configuration file globbing can now use simple pattern matching. - The protocol version (eg: HTTP/1.1) in the request line parsing is now case insensitive. - ap_snprintf() can now distinguish between an output which was truncated, and an output which exactly filled the buffer. - Add ProtocolReqCheck directive, which determines if Apache will check for a valid protocol string in the request (eg: HTTP/1.1) and return HTTP_BAD_REQUEST if not valid. - Versions of Apache prior to 1.3.26 would silently ignore bad protocol strings, but 1.3.26 included a more strict check. This makes it runtime configurable. - Added support for Berkeley-DB/4.x to mod_auth_db. - httpd -V will now also print out the compile time defined HARD_SERVER_LIMIT value. New features that relate to specific platforms: - Support Caldera OpenUNIX 8. - Use SysV semaphores by default on OpenBSD. - Implemented file locking in mod_rewrite for the NetWare CLib platform. Bugs fixed The following bugs were found in Apache 1.3.26 and have been fixed in Apache 1.3.27: mod_proxy fixes: - The cache in mod_proxy was incorrectly updating the Content-Length value from 304 responses when doing validation. - Fix a problem in proxy where headers from other modules were added to the response headers when this was already done in the core already. - In 1.3.26, a null or all blank Content-Length field would be triggered as an error; previous versions would silently ignore this and assume 0. 1.3.27 restores this previous behavior. - Win32: Fix one byte buffer overflow in ap_get_win32_interpreter when a CGI script's #! line does not contain a or (i.e. a line feed character) in the first 1023 bytes. The overflow is always a '' (string termination) character. Download Apache 1.3.27
