[SECURITY] [DLA 1495-1] git-annex security update

Package        : git-annex
Version        : 5.20141125+oops-1+deb8u2
CVE ID         : CVE-2017-12976 CVE-2018-10857 CVE-2018-10859
Debian Bug     : 873088

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.


    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.


    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.


    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

We recommend that you upgrade your git-annex packages.
