FreeBSD : svnserve is vulnerable to a local privilege escalation vulnerability via symlink attack. (f8a913cc-1322-11e3-8ffa-20cf30e32f6d)

Low Nessus Plugin ID 69546


The remote FreeBSD host is missing one or more security-related updates.


Subversion Project reports :

svnserve takes a --pid-file option which creates a file containing the process id it is running as. It does not take steps to ensure that the file it has been directed at is not a symlink. If the pid file is in a directory writeable by unprivileged users, the destination could be replaced by a symlink allowing for privilege escalation. svnserve does not create a pid file by default.

All versions are only vulnerable when the --pid-file=ARG option is used.


Update the affected packages.
