Debian DLA-1495-1 : git-annex security update
Medium Nessus Plugin ID 117296
SynopsisThe remote Debian host is missing a security update.
DescriptionThe 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
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
For Debian 8 'Jessie', these problems have been fixed in version
We recommend that you upgrade your git-annex packages.
