NOTE: The vulnerability may allow a local user to execute arbitrary code with root privileges if the utility is installed set-uid root. 2) A boundary error in the "dmail" utility when processing overly long mailbox names (over 1024 bytes) can be exploited to cause a stack-based buffer overflow. Successful exploitation of the vulnerabilities may allow execution of arbitrary code, but requires that the utilities are configured as a delivery backend for a mail transfer agent allowing overly long destination mailbox names. The vulnerabilities are reported in versions prior to 2007d. SOLUTION: Update to version 2007d. ftp://ftp.cac.washington.edu/imap PROVIDED AND/OR DISCOVERED BY: Reported by the vendor.
