Descriptions

envvars (aka envvars-std) in the Apache HTTP Server before 2.4.2 places a zero-length directory name in the LD_LIBRARY_PATH, which allows local users to gain privileges via a Trojan horse DSO in the current working directory during execution of apachectl.

envvars (también conocido como envvars-STD) en el servidor HTTP Apache antes de 2.4.2 establece un nombre de directorio de longitud cero en el LD_LIBRARY_PATH, que permite a usuarios locales conseguir privilegios a través de un caballo de Troya DSO en el directorio actual de trabajo durante la ejecución de apachectl.

Multiple vulnerabilities has been found and corrected in apache. Insecure handling of LD_LIBRARY_PATH was found that could lead to the current working directory to be searched for DSOs. This could allow a local user to execute code as root if an administrator runs apachectl from an untrusted directory. Possible XSS for sites which use mod_negotiation and allow untrusted uploads to locations which have MultiViews enabled. The updated packages have been upgraded to the latest 2.2.23 version which is not vulnerable to these issues.
