IMAP Proxy: Format string vulnerabilities — GLSA 200603-04

Format string vulnerabilities in IMAP Proxy may lead to the execution of arbitrary code when connected to malicious IMAP servers.

Affected Packages

net-mail/up-imapproxy on all architectures
Affected versions < 1.2.4
Unaffected versions >= 1.2.4

Background

IMAP Proxy (also known as up-imapproxy) proxies IMAP transactions between an IMAP client and an IMAP server.

Description

Steve Kemp discovered two format string errors in IMAP Proxy.

Impact

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.

Workaround

Only connect to trusted IMAP servers using IMAP Proxy.

Resolution

All IMAP Proxy users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-mail/up-imapproxy-1.2.4"
