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.

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)

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-2015-8560)

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.

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.

This update fixes the following security issues :

  - CVE-2015-8327: adds backtick and semicolon to the list     of illegal shell escape characters (bsc#957531).
    CVE-2015-8560: fixed code execution via improper     escaping of ; (bsc#957531).

This update for cups-filters fixes the following issues :

  - cups-filters-1.0.58-CVE-2015-8327-et_alii.patch adds     back tick and semicolon to the list of illegal shell     escape characters to fix CVE-2015-8327 and CVE-2015-8560     (boo#957531).

Michal Kowalczyk and Adam Chester discovered that missing input sanitising in the foomatic-rip print filter might result in the execution of arbitrary commands.

Adam Chester discovered that there was an injection vulnerability in foomatic-filters which is used by printer spoolers to convert incoming PostScript data into the printer's native format. This could lead to the execution of arbitrary commands.

The patch applied in DLA 365-1 prevented usage of (unescaped) backticks and this update complements the previous update by doing the same for semi-colons.

For Debian 6 Squeeze, this issue has been fixed in foomatic-filters version 4.0.5-6+squeeze2+deb6u12.

Till Kamppeter reports :

Cups Filters/Foomatic Filters does not consider semicolon as an illegal escape character.

Adam Chester discovered that the foomatic-filters foomatic-rip filter incorrectly stripped shell escape characters. A remote attacker could possibly use this issue to execute arbitrary code as the lp user.
