+ <background>
+ <p>
+ fetchmail is a utility that retrieves and forwards mail from
+ remote systems using IMAP, POP, and other protocols.
+ </p>
+ </background>
+ <description>
+ <p>
+ fetchmail does not properly validate UIDs coming from a POP3 mail
+ server. The UID is placed in a fixed length buffer on the stack, which
+ can be overflown.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ Very long UIDs returned from a malicious or compromised POP3
+ server can cause fetchmail to crash, resulting in a Denial of Service,
+ or allow arbitrary code to be placed on the stack.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There are no known workarounds at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All fetchmail users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=net-mail/fetchmail-6.2.5.2"</code>
