SynopsisThe remote host is missing a vendor-supplied security patch
DescriptionThe remote host is missing the patch for the advisory SuSE-SA:2003:045 (hylafax).
Hylafax is an Open Source fax server which allows sharing of fax equipment among computers by offering its service to clients by a protocol similar to FTP.
The SuSE Security Team found a format bug condition during a code review of the hfaxd server. It allows remote attackers to execute arbitrary code as root. However, the bug can not be triggered in hylafax' default configuration.
The 'capi4hylafax' packages also need to be updated as a dependency where they are available.
After the update has been successfully applied the hfaxd server has to be restarted by issuing the following command as root:
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.
