IMAP Proxy (also known as up-imapproxy) proxies IMAP transactions between an IMAP client and an IMAP server.
Steve Kemp discovered two format string errors in IMAP Proxy.
A remote attacker could design a malicious IMAP server and entice someone to connect to it using IMAP Proxy, resulting in the execution of arbitrary code with the rights of the victim user.
Only connect to trusted IMAP servers using IMAP Proxy.
All IMAP Proxy users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-mail/up-imapproxy-1.2.4"
