Description Cedric Buissart 2017-08-09 18:07:49 UTC 
Mercurial clients sometimes connect to URLs provided by the repository, as subrepositories, via the .hgsub file. 

A maliciously constructed ssh:// URL would cause Mercurial clients to run an arbitrary shell command. Such a URL could be generated by a malicious server, by a malicious user committing to a honest server (to attack another user of that server's repositories), or by a proxy server.

The vulnerability affects all clients, including those that use file://, http://, and ssh://.
