ConTEXt TEXutil contains a flaw that may allow a malicious local user to overwrite arbitrary files on the system. The issue is due to the texutil.pl script creating temporary files insecurely. It is possible for a user to use a symlink style attack to manipulate arbitrary files, resulting in a loss of integrity.
Upgrade to the current version, as it has been reported to fix this vulnerability. It is also possible to correct the flaw by implementing the following workaround(s): modify texutil.pl as specified in the advisory.
