Descriptions
CVS 1.12.x, when configured to use SSH for remote repositories, might allow remote attackers to execute arbitrary code via a repository URL with a crafted hostname, as demonstrated by "-oProxyCommand=id;localhost:/bar."
CVS 1.12.x, cuando se configura para que use SSH para repositorios remotos, podría permitir que atacantes remotos ejecuten código arbitrario mediante una URL de repositorio con un nombre de host manipulado, tal y como demuestra "-oProxyCommand=id;localhost:/bar.
Hank Leininger discovered that cvs did not properly handle SSH for remote repositories. A remote attacker could use this to construct a cvs repository that when accessed could run arbitrary code with the privileges of the user.
