Multiple vulnerabilities in Deliver
Deliver, multiple vulnerabilites
March 24, 2010
Deliver (http://deliver.sourceforge.net/), a mail delivery program
root as /usr/bin/deliver, is vulnerable to several race conditions that can be
exploited by a local attacker using symbolic links. On systems using Deliver
over NFS, these attacks can result in gaining root privileges via
of critical system files. On other systems, these attacks can result in
denial-of-service conditions and information disclosure. In addition, users can
deny service to other users by creating lockfiles for other users' mailboxes.
Users are advised to discontinue use of Deliver in the absence of a patch or
new release from the developer.
