Apache HTTP Server environment variable configuration file buffer overflow
| apache-env-configuration-bo (17384) |  High Risk |
Description:
Apache HTTP Server is vulnerable to a buffer overflow when expanding environment variables in an .htaccess or httpd.conf configuration file. By creating a malicious configuration file, a local attacker with apache privileges could overflow a buffer and execute arbitrary code on the system, once the malicious file is parsed.
