Detailsinfo

A vulnerability has been found in deepin-clone up to 1.1.2 and classified as problematic. Affected by this vulnerability is the function BootDoctor::fix of the file /tmp/repo.iso. The manipulation as part of a Symlink leads to a link following vulnerability. The CWE definition for the vulnerability is CWE-59. The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

deepin-clone before 1.1.3 uses a fixed path /tmp/repo.iso in the BootDoctor::fix() function to download an ISO file, and follows symlinks there. An unprivileged user can prepare a symlink attack there to create or overwrite files in arbitrary file system locations. The content is not attacker controlled. By winning a race condition to replace the /tmp/repo.iso symlink by an attacker controlled ISO file, further privilege escalation may be possible.

The weakness was published 07/04/2019 (oss-sec). It is possible to read the advisory at openwall.com. This vulnerability is known as CVE-2019-13228 since 07/04/2019.
