Affected: [UNKNOWN] lftp

It has been discovered that lftp up to and including version 4.8.3 does not properly sanitize remote file names, leading to a loss of integrity on the local system when reverse mirroring is used. A remote attacker may trick a user to use reverse mirroring on an attacker controlled FTP server, resulting in the removal of all files in the current working directory of the victim's system.

Affected: Ubuntu:14.04:LTS: lftp, Ubuntu:16.04:LTS: lftp, Ubuntu:18.04:LTS: lftp

It was discovered that LFTP incorrectly handled certain files. An attacker could possibly use this issue to cause a denial of service.
