22 <synopsis>

38 <p>
39 libspf2 is a library that implements the Sender Policy Framework,
40 allowing mail transfer agents to make sure that an email is authorized
41 by the domain name that it is coming from. Currently, only the exim MTA
42 uses libspf2 in Gentoo.

45 <description>
46 <p>
47 libspf2 uses a fixed-length buffer to receive DNS responses and does
48 not properly check the length of TXT records, leading to buffer
49 overflows.
50 </p>
51 </description>
52 <impact type="high">
53 <p>
54 A remote attacker could store a specially crafted DNS entry and entice
55 a user or automated system using libspf2 to lookup that SPF entry (e.g.
56 by sending an email to the MTA), possibly allowing for the execution of
57 arbitrary code.
58 </p>
59 </impact>
60 <workaround>
61 <p>
62 There is no known workaround at this time.
63 </p>
64 </workaround>
65 <resolution>
66 <p>
67 All libspf2 users should upgrade to the latest version:
68 </p>
69 <code>
70 # emerge --sync
71 # emerge --ask --oneshot --verbose &quot;&gt;=mail-filter/libspf2-1.2.8&quot;</code>
