Test ID:1.3.6.1.4.1.25623.1.0.51432
Category:Conectiva Local Security Checks
Title:Conectiva Security Advisory CLA-2003:675
Summary:NOSUMMARY
Description:Description:

The remote host is missing updates announced in
advisory CLA-2003:675.

ml85p[1] is a printer driver for the Samsung ML-85G and QL85G printer
models.

iDEFENSE published[2] the following vulnerabilities in some printer
related packages, including ml85p:

- mtink: this package is not distributed with Conectiva Linux


- escputil: the escputil program has a buffer overflow vulnerability
in the way it deals with a printer name. Long enough names can be
used to execute arbitrary code or crash the program. In Conectiva
Linux, escputil is NOT a SGID program, so it is not possible to
obtain higher privileges by exploiting this problem, but we are
nevertheless including a fix with this update.

- ml85p: this is a SUID root program and it creates temporary files
in an insecure way, which makes it vulnerable to a race condition
exploit. A local attacker could easily guess the name of this file
and create a symbolic link to anywhere on the system. If the target
exists, it will be overwritten
otherwise, it will be created with
0666 permissions (world writable).

There is, however, a condition for this to work: the attacker must be
able to execute ml85p. By default, it is only executable by root or
members of the sys group.


Solution:
The apt tool can be used to perform RPM package upgrades
by running 'apt-get update' followed by 'apt-get upgrade'
