Incomplete blacklist vulnerability in util.c in foomatic-rip in cups-filters 1.0.42 before 1.2.0 and in foomatic-filters in Foomatic 4.0.x allows remote attackers to execute arbitrary commands via ` (backtick) characters in a print job.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - cups-filters: foomatic-rip did not consider semicolon as illegal shell escape character (CVE-2015-8560)

  - Incomplete blacklist vulnerability in util.c in foomatic-rip in cups-filters 1.0.42 before 1.2.0 and in     foomatic-filters in Foomatic 4.0.x allows remote attackers to execute arbitrary commands via ` (backtick)     characters in a print job. (CVE-2015-8327)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

According to the versions of the foomatic packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Incomplete blacklist vulnerability in util.c in     foomatic-rip in cups-filters 1.0.42 before 1.2.0 and in     foomatic-filters in Foomatic 4.0.x allows remote     attackers to execute arbitrary commands via `     (backtick) characters in a print job.(CVE-2015-8327)

  - Incomplete blacklist vulnerability in util.c in     foomatic-rip in cups-filters 1.0.42 before 1.4.0 and in     foomatic-filters in Foomatic 4.0.x allows remote     attackers to execute arbitrary commands via a     (semicolon) character in a print job, a different     vulnerability than CVE-2015-8327.(CVE-2015-8560)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the versions of the foomatic packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - It was discovered that foomatic-rip failed to remove     all shell special characters from inputs used to     construct command lines for external programs run by     the filter. An attacker could possibly use this flaw to     execute arbitrary commands.(CVE-2015-8327)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that the unhtmlify() function of foomatic-rip did not correctly calculate buffer sizes, possibly leading to a heap-based memory corruption. A malicious attacker could exploit this flaw to cause foomatic-rip to crash or, possibly, execute arbitrary code.
(CVE-2010-5325)

It was discovered that foomatic-rip failed to remove all shell special characters from inputs used to construct command lines for external programs run by the filter. An attacker could possibly use this flaw to execute arbitrary commands. (CVE-2015-8327, CVE-2015-8560)

The remote OracleVM system is missing necessary patches to address critical security updates :

  - Also consider back tick and semicolon as illegal shell     escape characters.

  - CVE-2015-8327, (CVE-2015-8560)

  - Prevent foomatic-rip overrun (bug #1214534).

An updated foomatic package that fixes three security issues is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available from the CVE links in the References section.

Foomatic is a comprehensive, spooler-independent database of printers, printer drivers, and driver descriptions. The package also includes spooler-independent command line interfaces to manipulate queues and to print files and manipulate print jobs.

It was discovered that the unhtmlify() function of foomatic-rip did not correctly calculate buffer sizes, possibly leading to a heap-based memory corruption. A malicious attacker could exploit this flaw to cause foomatic-rip to crash or, possibly, execute arbitrary code.
