Synopsis
The remote Debian host is missing a security update.Description
The git-annex package was found to have multiple vulnerabilities when operating on untrusted data that could lead to arbitrary command execution and encrypted data exfiltration.CVE-2017-12976
git-annex before 6.20170818 allows remote attackers to execute arbitrary commands via an ssh URL with an initial dash character in the hostname, as demonstrated by an ssh://-eProxyCommand= URL, a related issue to CVE-2017-9800, CVE-2017-12836, CVE-2017-1000116, and CVE-2017-1000117.
CVE-2018-10857
git-annex is vulnerable to a private data exposure and exfiltration attack. It could expose the content of files located outside the git-annex repository, or content from a private web server on localhost or the LAN.
CVE-2018-10859
git-annex is vulnerable to an Information Exposure when decrypting files. A malicious server for a special remote could trick git-annex into decrypting a file that was encrypted to the user's gpg key. This attack could be used to expose encrypted data that was never stored in git-annex
For Debian 8 'Jessie', these problems have been fixed in version 5.20141125+oops-1+deb8u2.
We recommend that you upgrade your git-annex packages.
