[DSA216] DSA-216-1 fetchmail Vulnerability Scan
Vulnerability Scan Summary
Detailed Explanation for this Vulnerability Test
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.
