I am not fully convinced it needs a CVE.
It basically boils down to the old "logfile with content that might be controlled
by an attacker pasted raw to a terminal" issue.
Aren't these generally covered?
"without sanitizing non-printable characters" and so on.
There is some more control on the person who builds a specific package what is output
thant there usually is in logfiles though.
A rogue server is unlikely, however a malicious packager could echo "bad escape code"
in his build and then ask for help on our IRC channels or mailinglists with package Y on project X.
(anyone can create an account and build packages ... and asking for help is not uncommon)
e.g. with "look at logfile with: 'osc buildlog home:user foopackage standard i586'.)
