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. |

<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. |

<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. |

67 |
All libspf2 users should upgrade to the latest version: |
