Aren't these generally covered? CVE-2010-3928 CVE-2010-2713 CVE-2009-4487 "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'.) Ciao, Marcus
