Descriptions

Mercurial prior to 4.3 did not adequately sanitize hostnames passed to ssh, leading to possible shell-injection attacks.

Las versiones anteriores a la 4.3 de Mercurial no sanitizaban adecuadamente los nombres de host pasados a ssh, lo que conducía a posibles ataques de inyección de shell.

A shell command injection flaw related to the handling of "ssh" URLs has been discovered in Mercurial. This can be exploited to execute shell commands with the privileges of the user running the Mercurial client, for example, when performing a "checkout" or "update" action on a sub-repository within a malicious repository or a legitimate repository containing a malicious commit.
