[DRE-maint] Bug#836551: gitlab: short gpg key used in script

[D Haley]

Package: gitlab
Version: 8.10.5+dfsg-2
Severity: important

Dear Maintainer,

Your package appears to contain commands which use a short gpg-key
ID. These have recently been identified as potential security concerns,
due to a chance that the wrong key can be imported in the case of a
forced key-ID collision [1].

The affected file is:
 Scala.gitlab-ci.yml [2]


Please consider upgrading to a full key ID, for example, replace the command:

 gpg --keyserver <keyserver> --recv-keys <key_short_fingerprint> 

with

 gpg --keyserver  <keyserver> --recv-keys <key_full_id>

eg (not specific to your package):

 gpg --keyserver keyring.debian.org --recv-keys 05C3E651

becomes:

 gpg --keyserver keyring.debian.org --recv-keys 0x0D59D2B15144766A14D241C66BAF400B05C3E651


(Note the tail bytes are the same)

This has previously been forwarded to the security team, who advised to
report individual public bugs against each package - hence this bug.
