Subject Name:            Apache mod_alias
Subject Summary:         Apache HTTP Server
Subject Home:            http://httpd.apache.org/
Subject Versions:        * <= 1.3.28

Vulnerability Id:        CVE-2003-0542
Vulnerability Scope:     global (not OpenPKG specific)

Attack Feasibility:      run-time
Attack Vector:           local system
Attack Impact:           denial of service

Description:
    André Malo discovered buffer overflows [0] in the mod_alias and
    mod_rewrite modules of the Apache [1] webserver. These occurred if
    a regular expression with more than 9 capturing parenthesis was
    configured. To exploit this, an attacker would need to be able to
    locally create a carefully crafted configuration file (.htaccess or
    httpd.conf).
