Description:
Two vulnerabilities have been reported in UW-imapd, which can be exploited by malicious, local users to potentially gain escalated privileges, and by malicious people to potentially compromise a vulnerable system.
1) A boundary error in the "tmail" utility when processing overly long mailbox names (over 1024 bytes) can be exploited to cause a stack-based buffer overflow.
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.
