A local race condition exists in Exuberant Ctags. The software fails to properly set file permissions on temporary files. It may be possible for an attacker to use a symbolic link to the temporary file to overwrite any file on the system which could result in loss of integrity and/or availability.
Upgrade to version 3.2.4 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
