Mandrake Linux Security Advisory : hylafax (MDKSA-2005:177)
Low Nessus Plugin ID 19985
SynopsisThe remote Mandrake Linux host is missing one or more security updates.
Descriptionfaxcron, recvstats, and xferfaxstats in HylaFax 4.2.1 and earlier allows local users to overwrite arbitrary files via a symlink attack on temporary files. (CVE-2005-3069)
In addition, HylaFax has some provisional support for Unix domain sockets, which is disabled in the default compile configuration. It is suspected that a local user could create a fake /tmp/hyla.unix socket and intercept fax traffic via this socket. In testing for this vulnerability, with CONFIG_UNIXTRANSPORT disabled, it has been found that client programs correctly exit before sending any data.
The updated packages have been patched to correct these issues.
SolutionUpdate the affected packages.
