CVE-2007-2448

Subversion 1.4.3 y versiones anteriores no implementa apropiadamente el privilegio "acceso parcial" para usuarios que tienen acceso a rutas cambiadas pero no rutas copiadas, lo cual permite a usuarios remotos autenticados obtener información confidencial (propiedades de revisión) mediante svn (1) propget, (2) proplist, ó (3) propedit.

It was discovered that Subversion incorrectly handled certain 'partial access' privileges in rare scenarios. Remote authenticated users could use this flaw to obtain sensitive information (revision properties). This issue only applied to Ubuntu 6.06 LTS. It was discovered that the Subversion mod_dav_svn module for Apache did not properly handle a named repository as a rule scope.

It was discovered that the Subversion mod_dav_svn module for Apache incorrectly handled the walk function. Remote authenticated users could use this flaw to cause the service to crash, leading to a denial of service. It was discovered that Subversion incorrectly handled certain memory operations. Remote authenticated users could use this flaw to consume large quantities of memory and cause the service to crash, leading to a denial of service.
