SUSE-SA:2003:001: fetchmail

High Nessus Plugin ID 13775


The remote host is missing a vendor-supplied security patch


The remote host is missing the patch for the advisory SUSE-SA:2003:001 (fetchmail).

fetchmail is used to download emails from POP-, IMAP-, ETRN- or ODMR- servers.
Stefan Esser of e-matters reported a bug in fetchmail's mail address expanding code which can lead to remote system compromise.
When fetchmail expands email addresses in mail headers it doesn not allocated enough memory. An attacker can send a malicious formatted mail header to exhaust the memory allocated by fetchmail to overwrite parts of the heap. This can be exploited to execute arbitrary code.

There is no temporary fix known. Please install the new packages from our FTP servers.

Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement.
Then, install the package using the command 'rpm -Fhv file.rpm' to apply the update.
