[DSA216] DSA-216-1 fetchmail |

DSA-216-1 fetchmail Detailed Explanation for this Vulnerability Assessment Stefan Esser of e-matters discovered a buffer overflow in fetchmail, an SSL enabled POP3, APOP and IMAP mail gatherer/forwarder. When fetchmail retrieves a mail all headers that contain addresses are searched for local addresses. If a hostname is missing, fetchmail appends it but doesn't reserve enough space for it. This heap overflow can be used by remote attackers to crash it or to execute arbitrary code with the rights of the user running fetchmail. For the current stable distribution (woody) this problem has been fixed in version 5.9.11-6.2 of fetchmail and fetchmail-ssl. For the old stable distribution (potato) this problem has been fixed in version 5.3.3-4.3. For the unstable distribution (sid) this problem has been fixed in version 6.2.0-1 of fetchmail and fetchmail-ssl. We recommend that you upgrade your fetchmail packages.
