CVE-2013-1862

mod_rewrite.c in the mod_rewrite module in the Apache HTTP Server 2.2.x before 2.2.25 writes data to a log file without sanitizing non-printable characters, which might allow remote attackers to execute arbitrary commands via an HTTP request containing an escape sequence for a terminal emulator.

It was found that mod_rewrite did not filter terminal escape sequences from its log file. If mod_rewrite was configured with the RewriteLog directive, a remote attacker could use specially-crafted HTTP requests to inject terminal escape sequences into the mod_rewrite log file. If a victim viewed the log file with a terminal emulator, it could result in arbitrary command execution with the privileges of that user (CVE-2013-1862).

This update for the Apache Web Server introduces directives to control two protocol options:

* HttpContentLengthHeadZero: Allow responses to HEAD request with
  Content-Length of 0
* HttpExpectStrict: Allow the administrator to control whether clients
  must send '100-continue'

MODULE_MAGIC_NUMBER_MINOR has been increased to 24, as this change is not forward-compatible. Modules built against this release might not work correctly with older releases of the Apache Web Server.
