Mandrake Linux Security Update Advisory
________________________________________________________________________
Package name: hylafax
Advisory ID: MDKSA-2002:055
Date: August 28th, 2002
Affected versions: 7.1, 7.2, 8.0, 8.1, 8.2, Corporate Server 1.0.1
________________________________________________________________________
Problem Description:
Numerous vulnerabilities in the HylaFAX product exist in versions prior
to 4.1.3. It does not check the TSI string which is received from
remote FAX systems before using it in logging and other places. A
remote sender using a specially formatted TSI string can cause the
faxgetty program to segfault, resulting in a denial of service. Format
string vulnerabilities were also discovered by Christer Oberg, which
exist in a number of utilities bundled with HylaFax, such as faxrm,
faxalter, faxstat, sendfax, sendpage, and faxwatch. If any of these
tools are setuid, they could be used to elevate system privileges.
Mandrake Linux does not, by default, install these tools setuid.
Finally, Lee Howard discovered that faxgetty would segfault due to a
buffer overflow after receiving a very large line of image data. This
vulnerability could conceivably be used to execute arbitrary commands
on the system as root, and could also be exploited more easily as a
denial of sevice.
