Description:
infamous41md has reported a vulnerability in UW-imapd, which can be exploited by malicious users to cause a DoS (Denial of Service) or compromise a vulnerable system.
The vulnerability is caused due to a boundary error in the "mail_valid_net_parse_work()" function when copying the user supplied mailbox name to a stack buffer. This can be exploited to cause a stack-based buffer overflow via a specially crafted mailbox name that contains an single opening double-quote character, without the corresponding closing double-quote.
Successful exploitation allows arbitrary code execution, but requires valid credentials on the IMAP server.
The vulnerability has been reported in version imap-2004c1. Prior versions may also be affected.
