Apache httpd 1.3.31 Released

Apache httpd 1.3.31 was released on 11th May 2004 and is now the latest version of the Apache httpd 1.3 server. The previous release was 1.3.29, released on the 29th October 2003. See what was new in Apache httpd 1.3.29.

Apache httpd 1.3.31 is available for download

This is a security, bug fix and minor upgrade release. Due to security issues, any sites using versions of Apache httpd 1.3 prior to Apache httpd 1.3.31 should upgrade to Apache httpd 1.3.31. Read more about the other security issues that affect Apache httpd 1.3.

Security issues

  • When using multiple listening sockets, a denial of service attack is possible on some platforms due to a race condition in the handling of short-lived connections. This issue is known to affect some versions of AIX, Solaris, and Tru64; it is known to not affect FreeBSD or Linux. The Common Vulnerabilities and Exposures project has assigned the name CAN-2004-0174 to this issue.
  • Arbitrary client-supplied strings can be written to the error log which can lead to exploits of certain terminal emulators. The Common Vulnerabilities and Exposures project has assigned the name CAN-2003-0020 to this issue.
  • mod_digest was not checking the nonce value returned by clients; use of mod_auth_digest is recommended in place of mod_digest. The Common Vulnerabilities and Exposures project has assigned the name CAN-2003-0987 to this issue.
  • Allow/Deny rules using IP addresses without a netmask were not interpreted correctly on big-endian 64-bit platforms. The Common Vulnerabilities and Exposures project has assigned the name CAN-2003-0993 to this issue.

New features

The following new features have been added since 1.3.29:

  • the source code is now licensed under the Apache License, Version 2.0
  • mod_whatkilledus, mod_backtrace: New diagnostic modules which log information about child process crashes
  • mod_log_forensic: New module which performs "forensic" logging

Bugs fixed

The following bugs have been fixed in 1.3.31:

  • mod_usertrack: fix segfault if CookieName was omitted (BZ#24483); fixed to not overwrite other cookies (BZ#26002), and to not inspect the Cookie2 request header (BZ#11475)
  • mod_rewrite: fix double-slash bug in RewriteBase; export the REMOTE_PORT variable (BZ#25882); fail on lookup keys containing a newline are used with external rewrite maps (BZ#14453)
  • mod_include: fix handling of expressions which begin with an escaped token
  • fix a memory corruption problem in the ap_custom_response function

Under development

The 1.3.30 release process was abandoned last month after a short period of testing, so that the mod_digest security issue could be resolved. The new 1.3.31 release candidate tarball gained more attention than normal after a story posted to Slashdot announced that the tarball produced was in fact the final release. No vetoes were posted for the tarball so the release went ahead otherwise as normal.

1.3.31's Release Manager Jim Jagielski proposed that the apache-1.3 CVS repository be migrated to a Subversion repository. Subversion has been under evaluation at apache.org for some time; several ASF projects in the Incubator process have been using the Subversion repository which has been set up, notably SpamAssassin.
