Mandrake Linux Security Advisory : hylafax (MDKSA-2006:015)
High Nessus Plugin ID 20794
SynopsisThe remote Mandrake Linux host is missing one or more security updates.
DescriptionPatrice Fournier discovered the faxrcvd/notify scripts (executed as the uucp/fax user) run user-supplied input through eval without any attempt at sanitising it first. This would allow any user who could submit jobs to HylaFAX, or through telco manipulation control the representation of callid information presented to HylaFAX to run arbitrary commands as the uucp/fax user. (CVE-2005-3539, only 'notify' in the covered versions)
Updated packages were also reviewed for vulnerability to an issue where if PAM is disabled, a user could log in with no password.
In addition, some fixes to the packages for permissions, and the %pre/%post scripts were backported from cooker. (#19679)
The updated packages have been patched to correct these issues.
SolutionUpdate the affected packages.
