Debian Security Advisory DSA-071-1 security@debian.org

Package : fetchmail
Problem type : memory corruption
Debian-specific: no
Salvatore Sanfilippo found two remotely exploitable problems in
fetchmail while doing a security audit. In both the imap and pop3
code the input is not verified and used to store a number in an
array. Since no bounds checking is done this can be used by an
attacker to write arbitrary data in memory. An attacker can use this
if we can get a user to transfer mail from a custom imap or pop3
server he controls.
This has been fixed in version 5.3.3-3.
wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.
Debian GNU/Linux 2.2 alias potato
