Fix ADC security issue
Dylan Alex Simon discovered and reported a directory traversal flaw in
the way Gitolite restricted access to admin defined commands ("ADC"). An
authenticated attacker could execute arbitrary code with privileges of
Gitolite server user using specially crafted command name.
The flaw does not affect default Gitolite installations. Users who have
enabled ADC in their configurations are advised to install the updated
package which includes a fix to resolve the issue.
