NVD Description

Note: Versions mentioned in the description apply only to the upstream libguestfs-rsync package and not the libguestfs-rsync package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

An integer overflow flaw which could lead to an out of bounds write was discovered in libssh2 before 1.8.1 in the way SSH_MSG_CHANNEL_REQUEST packets with an exit signal are parsed. A remote attacker who compromises a SSH server may be able to execute code on the client system when a user connects to the server.
