Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Data exfiltration attack

EUVDB-ID: #VU13536

Risk: Low

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-10857

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The vulnerability exists due to private data exfiltration attack. A remote attacker can run git-annex addurl --relaxed file:///etc/passwd and commit this to the repository in some out of the way place. After the victim's git repository receives that change, git-annex follows the attacker-provided url to private data, which it stores in the git-annex repository. From there it transfers the content to the git-annex repository that the attacker has access to.

Mitigation

Update the affected packages.
