Descriptions

The req_check_access function in the mod_authz_svn module in the httpd server in Apache Subversion before 1.8.16 and 1.9.x before 1.9.4 allows remote authenticated users to cause a denial of service (NULL pointer dereference and crash) via a crafted header in a (1) MOVE or (2) COPY request, involving an authorization check.

La función req_check_access en el módulo mod_authz_svn en el servidor httpd en Apache Subversion en versiones anteriores a 1.8.16 y 1.9.x en versiones anteriores a 1.9.4 permite a usuarios remotos autenticados provocar una denegación de servicio (referencia a puntero NULL y caída) a través de una cabecera manipulada en una petición (1) MOVE o (2) COPY, involucrando una verificación de autorización.

USN-3388-1 fixed several vulnerabilities in Subversion. This update provides the corresponding update for Ubuntu 12.04 ESM. Ivan Zhakov discovered that Subversion did not properly handle some requests. A remote attacker could use this to cause a denial of service. Various other issues were also addressed.
