[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:
- 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 *)
