Multiple format string flaws were found in Condor: a) when the XML message log format was requested in Condor submit job by remote Condor user and that user attempted to write a specially-crafted message into user log file via condor_hold tool it could lead to condor_schedd daemon crash, or, potentially arbitrary code execution with the privileges of the 'condor' user [*]. Also this way an attacker could potentially prevent other Condor jobs from being scheduled and ever executed, b) request for file transfer by remote Condor user to transmit a file, with specially-crafted name, could lead to child process of condor_schedd daemon to crash (repeated process, where condor_schedd daemon would fork a child process to handle the request, the child to crash, while trying to handle it and condor_schedd daemon to fork another child since the particular Condor job still have not been completed successfully). Upstream bug report (mentioning only one attack vector): [1] https://condor-wiki.cs.wisc.edu/index.cgi/tktview?tn=2660 General upstream patch (addressing among these flaws also couple of compiler warning problems): [2] http://condor-git.cs.wisc.edu/?p=condor.git;a=commitdiff;h=5e5571d1a431eb3c61977b6dd6ec90186ef79867 -- [*] Arbitrary code execution was possible only on systems, where Condor daemons were not compiled with FORTIFY_SOURCE protection mechanism. On systems with this protection enabled, particular flaw would lead to Condor service crash only.
