Descriptions
Apache Subversion's mod_dontdothat module and HTTP clients 1.4.0 through 1.8.16, and 1.9.0 through 1.9.4 are vulnerable to a denial-of-service attack caused by exponential XML entity expansion. The attack can cause the targeted process to consume an excessive amount of CPU resources or memory.
El módulo mod_dontdothat y los clientes HTTP en su versión 1.4.0 hasta la 1.8.16 y 1.9.0 hasta la 1.9.4 de Apache Subversion son vulnerables a un ataque de denegación de servicio (DoS) provocado por la expansión exponencial de la entidad XML. El ataque puede provocar que el proceso objetivo consuma una cantidad excesiva de recursos de la CPU o memoria.
Joern Schneeweisz discovered that Subversion did not properly handle host names in 'svn+ssh://' URLs. A remote attacker could use this to construct a subversion repository that when accessed could run arbitrary code with the privileges of the user. Daniel Shahaf and James McCoy discovered that Subversion did not properly verify realms when using Cyrus SASL authentication. A remote attacker could use this to possibly bypass intended access restrictions. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. Various other issues were also addressed.
