Vulnerability Assessment Details

[DSA376] DSA-376-2 exim

Vulnerability Assessment Summary
DSA-376-2 exim

Detailed Explanation for this Vulnerability Assessment

A buffer overflow exists in exim, which is the standard mail transport
agent in Debian. By supplying a specially crafted HELO or EHLO
command, a possible hacker could cause a constant string to be written past
the end of a buffer allocated on the heap. This vulnerability is not
believed at this time to be exploitable to execute arbitrary code.
For the stable distribution (woody) this problem has been fixed in
exim version 3.35-1woody2 and exim-tls version 3.35-3woody1.
For the unstable distribution (sid) this problem has been fixed in
exim version 3.36-8. The unstable distribution does not contain an
exim-tls package.
We recommend that you update your exim or exim-tls package.
