Descriptions

Buffer overflow in Apache 2.0.50 and earlier allows local users to gain apache privileges via a .htaccess file that causes the overflow during expansion of environment variables.

Desbordamiento de búfer en Apache 2.0.50 y anteriores permite a usuarios locales ganar privilegios mediante un fichero .htaccess que causa un desbordamiento durante la expansión de variables de entorno.

Two new vulnerabilities have been discovered in Apache. Through the testing of Apache by using the Codenomicon HTTP Test Tool, the ASF Security Team has discovered a bug in the apr-util library, which can lead to arbitrary code execution. SITIC have discovered that Apache suffers from a buffer overflow when expanding environment variables in configuration files such as .htaccess and httpd.conf, leading to possible privilege escalation. These vulnerabilities affect versions 2.0.35 through 2.0.50.
