Mandrake Linux Security Update Advisory ________________________________________________________________________
Package name: fetchmail Date: August 31st, 2001 Advisory ID: MDKSA-2001:072
Affected versions: 7.1, 7.2, 8.0, Corporate Server 1.0.1 ________________________________________________________________________
Problem Description:
A vulnerability was found by Salvatore Sanfilippo in both the IMAP and POP3 code of fetchmail where the input is not verified and no bounds checking is done. This can be exploited by a remote attacker to write arbitrary data into memory. The attacker must have control of the mail server the client is connecting to via fetchmail in order to exploit this vulnerability. ________________________________________________________________________

To upgrade automatically, use MandrakeUpdate.
If you want to upgrade manually, download the updated package from one of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm".
You can download the updates directly from one of the mirror sites listed at:
http://www.linux-mandrake.com/en/ftp.php3.
Updated packages are available in the "updates/[ver]/RPMS/" directory. For example, if you are looking for an updated RPM package for Mandrake Linux 8.0, look for it in "updates/8.0/RPMS/". Updated source RPMs are available as well, but you generally do not need to download them.
Please be aware that sometimes it takes the mirrors a few hours to update.
