Slackware These updates fix local vulnerabilities that could allow userswho can create or edit Apache config files to gain additionalprivileges.

[slackware-security]  apache security update (SSA:2003-308-01)

Apache httpd is a hypertext transfer protocol server, and is used
by over two thirds of the Internet's web sites.

Upgraded Apache packages are available for Slackware 8.1, 9.0, 9.1,
and -current.  These fix local vulnerabilities that could allow users
who can create or edit Apache config files to gain additional
privileges.  Sites running Apache should upgrade to the new packages.

In addition, new mod_ssl packages have been prepared for all platforms,
and new PHP packages have been prepared for Slackware 8.1, 9.0, and
- -current (9.1 already uses PHP 4.3.3).  In -current, these packages
also move the Apache module directory from /usr/libexec to
/usr/libexec/apache.  Links for all of these related packages are
provided below.

More details about the Apache issue may be found in the Common
Vulnerabilities and Exposures (CVE) database:

   http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0542


Here are the details from the Slackware 9.1 ChangeLog:
+--------------------------+
Mon Nov  3 20:06:29 PST 2003
patches/packages/apache-1.3.29-i486-1.tgz:  Upgraded to apache-1.3.29.
  This fixes the following local security issue:
    o CAN-2003-0542 (cve.mitre.org)
      Fix buffer overflows in mod_alias and mod_rewrite which occurred if
      one configured a regular expression with more than 9 captures.
  This vulnerability requires the attacker to create or modify certain
  Apache configuration files, and is not a remote hole.  However, it could
  possibly be used to gain additional privileges if access to the Apache
  administrator account can be gained through some other means.  All sites
  running Apache should upgrade.
  (* Security fix *)
