imap-uw IMAP Package POP Predictable Lock File DoS
Local Access Required Denial of Service

imap-uw contains a flaw that may allow a local denial of service. The problem is that the popd daemon creates lock files with predictable names, which could allow a malicious user to lock mailboxes of other users.

- 漏洞讨论

Vulnerabilities exist in a number of pop3 daemon implementations, having to do with their creation of lock files. Affected include Qualcomm's qpopper, and the popd included as part of the imap-4 rpm from RedHat. Lockfiles in both implementation are created with consistent local file names; the RedHat popd in /tmp, with a fairly random name (albeit consistent for a given user), and in the mail spool directory, with the user name prepended by a "." and appended with ".pop". Creation of either of these files will prevent the popd user from being able to establish a connection to retrieve their mail.

The FreeBSD port of imap-uw contains this vulnerability. It is not, however, included as a standard part of a FreeBSD install.
